I built this computer because I was just not getting enough out of my MacBook Pro; I could only run games at low settings and the operating system limited which games were compatible with my Mac. I grabbed an old Gateway mid-tower computer and began my research. It took me about 3 weeks of research for me to finally order the computer parts; at first, I was going to get an Intel i5 quad-core processor, later realizing that nice GPU is more important for gaming than a nice CPU was. I then looked at AMD processors and loved the prices - even though they take up more power and get considerably warmer than Intel processors, you just can't beat their prices.
I would highly recommend all of the parts I got except for the motherboard; it only supports up to 1333MHz ram (even though 1333 is fast enough for me, you can get much faster an almost identical cost) and it only has two 4-pin fan slots (they both can also work as 3 pin fan slots) - I was hoping on getting a third fan later on.
I love the GeForce graphics card! It runs every game I have tried (including GTA V) at high/ultra settings with 60+ FPS. The 4gb version (the one that I got) does not give a noticeable advantage over the 2gb version on 99.99% of games but I got it anyway because it was only $15 more than the 2gb edition (because of the sale for $200). The card came with an awesome looking black backplate that protects the card and looks good while doing so. (This card is compatible with Windows XP / Vista / 7 / 8 / 8.1 / and 10, making it a good choice if you have an old computer and can't or don't want to upgrade - and all of the other parts ran Windows Vista fine until I upgraded to 10)
I used the hard drives, case, optical drive, and case fan from the old Gateway computer and found an old Windows 7 license and installation disk that I used to upgrade to Windows 10. I did not order the graphics card until I got everything else working and Windows 10 installed because the motherboard has a built in graphics card that is good enough to surf the internet and search for files.
I used MSI Afterburner to calculate temperatures and to adjust the fan speed curve on my GPU (put on chart below) and Furmark to stress my CPU and GPU (Furmark is, in my opinion, by far the best GPU stressor out there and also has a CPU stressor function that is also pretty good)
Temperature in Cº: 20º 30º 45º 60º 65º 75º 76º
Percent of Fan Speed: 5% 10% 40% 70% 80% 90% 100%
