This is my second machine from UK Gaming Computers. As before I am pretty impressed with the service. The people that I dealt with were friendly and knowledgeable and took the time to chat with me before I ordered so that I could make sure that I chose the right parts for my needs. There was no pressure to pay for extra stuff that I did not need and I believe that I was given very honest answers to my questions.<br><br>My aim was to get a PC that was going to last most of this new console generation. In the end this meant the Achilles I5 machine with a little bit of customization. I upgraded the power supply to a a 750 watt Corsair modular one that was gold-rated. I also swapped in 8GB of Corsair Vengeance RAM and popped the whole thing inside the Corsair Vengeance C70 case. <br><br>The build took around two weeks (I chose the standard 5-10 days) and I was kept informed of what was going on via emails. The PC was delivered to me at a time and day of my choosing. The packing was very good and the PC was in perfect condition when it arrived. A special foam-bag was used inside the case in order to keep the parts fixed in place and the external packing was very good quality.<br><br>I have tested the PC out with a large number of games and it runs really well. I have played the new Assassin's Creed, Splinter-Cell and Batman games on it (all of which came with the graphics card due to an offer Nvidia had on at the time) and they run perfectly. I am able to pop them on ultra and still get 60fps on a 1080 * 1920. Older games seem to run fine too; so far all the stuff in my Steam library has been working very well so I am extremely pleased with that.<br><br>The only issue that I do have is that there seems to be some rather noisy capacitor squeal coming from the graphics card while it is under load. The noise is a kind of metallic buzzing - something like you would get from an electric shaver. Its not a normal noise for this kind of PC to make (my partner has another machine that also has a GTX770 in it and there is no noise of this kind). The noise is pretty loud depending on which game you are playing. Batman seems to be the worse, with the noise getting loud enough to make it hard to hear the voices of the characters at times. I spoke to UK Gaming Computers about it and they just told me it was capacitor squeal and that there was a good chance that my card might grow out of it in a couple of months. Having looked around the internet it seems that most people consider this a reason to RMA a card which makes me a little annoyed as I payed a lot of money (£1130.00) for the PC so I really would rather it was not doing an impression of a dentists drill while I am trying to game on it. That said, UK Gaming Computers have offered to RMA the card if it is still there in a few months time. I guess I am just stuck with a very noisy buzz until then unless it goes away of its own accord.<br><br>Anyhow, in conclusion I am pretty happy with the machine. The build quality is nice and the performance in games is great. I'm a bit puzzled as to how UK Gaming Computers testing failed to notice that my machine buzzes so much - it was obvious to me the second I booted up a game. I can only assume that they did not run any games and/or graphically intensive stuff on it before shipping it out to me. However, overall I am happy with the machine provided that I can get this buzzing noise sorted before long.
