Buying 866 dollar gamer PC, is it worth it?

[Muggah]

Hello everyone, I was thinking about buying this PC, but didn't know if I should or not.. I will be gaming with it for sure, games like Diablo 3, Battlefield 3, just modern day games. But is it powerful enough.. Anyhelp would be appreciated, thanks! Here's are all my specs:


Found a AMD CPU for my budget with a monitor.. Any Advice any one would be AWESOME!

Motherboard GIGABYTE GA-990FXA-UD5 Motherboard S.AM3 AMD 990FX ATX 4D.DDR3,3PCIE 16X/2PCIE 1X/PCI RAID,1XGBLAN,1394,USB 3,SATA 3

Note: I could change the Power supply to a Antec, or do I need to. One more thing is do I need to upgrade the W in the power supply?

Not sure about the power supply and you're going to want a better GPU for gaming but the rest of the system looks pretty solid. I assume you don't want to overclock your CPU (which you can't due to the H77 chipset). Also, what's up with your RAM config?

Depends on your monitor's resolution. That should play BF3 at 1080p with medium settings I think. I have a 6770 and have to go with low across the board.
