Let customers speak for us
I contacted game force.ie looking for GPU for a custom pc and Jason from gameforce was extremely helpful and gave very solid advice what would work and wouldn't and help me very much,even better the GPU I ordered would be delayed coming on time and got better spec at same price.so very impressed with service. Will deal with again for anything pc related and recommend
I have always viewed my self as computer expert - but with a small "e". My existing Alienware dates from 2009. I have upgraded it myself over the years, but I ran out of options about 2020. In recent years I have not been able to run MSFS with any sort of fluidity, nor to use the most recent Photoshop software.
I have been waiting for the last few years for Intel to get their act together, but as they are way behind in process development and still insist on perhaps 1 1/2 generations of CPU per socket, I have given up on them. The obvious alternative is AMD, who have really had their act together in the last few years. The AM5 socket should be good until 2027, which gives me a lot of headroom.
I could not have possibly put together my PC with Jason's help.
Our experience with Gameforce was from purchasing over 100 office pcs and from being assisted with donating our old office pcs to charity. I came to gameforce through a recommendation from a Chamber of Commerce member and I spoke to the owner of Gameforce who came across as experienced so I agreed to a meeting. At the meeting there was a number of promises made and at the end of the day Gameforce honoured each of the promises and even paid for 50% of the secure data destruction cost allowing us to donate the pcs to a charity of our choosing. Given their name I was not expecting a company who would be able to supply and install our 100+ pcs whilst at the same time organise the removal as well as the security to ensure the data destruction to a professional level as they did. The main man at Gameforce comes from a corporate background and has the experience which is how this business is so strong and professional. I cannot fault any aspect of the contract and I would recommend Gameforce to any medium sized business looking to replace older pcs. Goodwork , Professional and Trustworthy
Over the course of 2 weeks we received the required information to allow us to make a decision which allowed us to save over €15,000 when replacing our 6 year old office pcs. The secure destruction of the data was handled for us as well as the collection of over 100 of our 2019 office pcs with the new pcs delivered over the week before the old pcs were collected allowing us the time to ensure a timely switch over. I was not expecting them to be able to organise this service and I admit I was surprised they were able to keep to the terms of the agreement but they did. I would have no hesitation in recomending gameforce to any medium sized business replaced 50+ pcs or more as the experience of this company and the services they offer are far beyond what would normally be expected from a local supplier. We received certificates of destruction from a third party company with photos and video showing the destruction and recycling of the hdds in our old pcs and the charity donation of our old pcs all organised by gameforce on our behalf. On top of this we saved close to €15,000 on the contract with Gameforce coming in far lower in price and offering a comparative service to larger companies who were charging 3 times the price. First class service from beginning to end and I can tell you I would recommend them to other companies who need to replace and dispose of older generation pcs. We chose not to take any return on the old pcs against our new pcs as we wanted to donate the pcs to charity and gameforce also donated their time and paid 50% of the cost to securely destroy the data which they did not have to do. They are an Irish company with International experience and the main guy there knows what he is doing and has vast experience with some of the biggest companies across the world. Truly a world class service from start to finish.
Well taken care of all the way. Thanks
Faultless experience. I got what I asked for quick and without any fuss
Quick Delivery and really good experience. gameforce was recommended to me by a friend from Canada who had purchased from this company before they moved to Canada last year. They recommended this business as it seems they had an issue when in Canada and gameforce was able to sent a component to help them diagnose a problem and then organised a local company in Canada to fit a graphics card. I must say I was surprised at how they were able to do that and I decided to order a gaming rig after 2 exchanges with them. They did explain to me that providing service in Canada was not always possible and by coincidence they told me that a previous staff member of gameforce was living only 40km away from my friend in Canada so the magic of their reach across the world was shattered.
My Gaming Rig arrived in about 8 days with my only concern being dpd who tried to deliver to my neighbour. Once I got my rig the setup was straight forward and everything I needed was sent in the box. Now after 3 weeks I can say the pc has performed to the level I expected if not a little further. I am very happy with the pc and with the purchase support I received before and during my purchase.
I did get a nice free upgrade with a Samsung pro m.2 being provided. I had explained to them of an issue I had with my previous pc were the m.2 had over heated so they upgrade the m.2 to a Samsung with a heatsink. They made no extra charge and never made me aware of this with the only mention of it coming in the email I got showing the components in the pc.
I think this company are a gem and I will be recommending them to all of my friends.
Good knowledge , Good Service and an overall good experience
What performance and breath taking speed . I bought so i could work from home as i did not have the space for a workstation. I took advice and it made a better machine and saves me money.
Good performance , quick delivery and very helpful support before during and after my purchase.
Well built pc as expected with better than expected performance from an integrated Radeon gpu. Clearly the 16GB of DDR4 memory makes the difference with good fps on fortnite. I tried with 8GB out of curiosity and the performance was sluggish so the 16GB was the right choice and their advice was invaluable
Educational order of 62 PCs were needed during a 3 day window and the team made everything go to plan with no changes. PCs were delivered onsite and they sent a technician with the PCs to help with the setup. They also organised for our security tags to be added to the PCs during the build stage which saved up time. The contract deadline was tight but they were able to deliver within 21 days and were true to their word. PCs are setup now for almost 3 months with no issues and my emails get answered usually within 1 hour even after the order was delivered. Our next contract will be going to gameforce i would expect given the collect and return warranty and the level of support and professionalism shown before , during and after delivery.
This was my third pc from them and as usual the communication was superb and the new workstation arrived in just under 10 days which they had kept me updated about as they knew I was eager to take delivery. I knew what I needed however they made a number of small changes after I accepted their advice and for the same money I got a more powerful workstation. This is the only company I trust to build my workstations as they understand the importance of good service.
I ordered on a Monday and I received the following Friday. I was notified of the update to the new AMD RYZEN cpu which was added to my pc for no extra charge and they still completed the delivery inside 5 days. I am very happy with the level of service and when I needed another pc delivered to an address in Germany they were able to organise this with the pc delivered to our offices in Germany 4 days with DHL. This was the first occasion were we had worked with this Irish company but it will not be the last given the impeccable service and quality products they supplied in double quick time.
Taking their advice saved me €€€ and got me a better pc for the task I had in mind. Excellent communications with most messages answered within 15 minutes. I cannot fault the pc or the service I received.
Arrived in 5 days. Good specs for my entertainment server. Excellent advice with rhe help to choose the right specs. Saved me over €450 as my design was overkill in their words
