CyberpowerPC Gamer Xtreme 1343 Desktop PC Intel Core i5 3570k(3.40GHz) 16GB DDR3 1TB HDD Capacity Nvidia Geforce GTX 560 2GB PCI-e Graphics Windows 7 Home Premium 64-Bit
this is all for $1000
The GTX 560 is a rebadged GTX 460 1GB that is highly factory overclocked. A stock GTX 460 is clocked 675-1350-1800 while a stock GTX 560 is clocked at 810-1620-2000. That is the only difference.
I have had my GTX 460 1GB since the week the 460 was released close to 2 years ago and from day 1 I have had it overclocked to 820-1640-2000.
It has been a great card that lets me max almost every game I play at 1920 x 1080. Skyrim, Deus Ex, Dragon Age Origins/II, Fallout 3/NV, Far Cry/2 ect. I do not really play first person shooters though and I don't expect it would do so well in some of the more demanding games like Metro 2033 or BF3. So hopefully this gives you a reasonable expectation of what a GTX 560 can do. If you want to play the newest, most demanding games you might want to try for a GTX 560 Ti or an HD 7850.
I am finally going to upgrade when the GTX 660 / 660 Ti come out at least if they are as good as I expect them to be.
