Who the fuck would dish out for any of the 7xxx series when you can wait for te 8xxx series that's being released this year?
Uour motherboard is running on an older socket, 990 is better. Look at the GA-990fx-ud7.
I'd say the GTX 660 2gb from EVGA, here is one i found on newegg it has good reviews - EVGA SuperClocked 02G-P4-2662-KR GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card - Newegg.com
You're underpowering your system. I would return that PSU and get at the very least a 750W. Either of these would be an awesome replacement:
CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Compatible with Core i7 Power Supply - Newegg.com
RAIDMAX HYBRID 2 RX-730SS 730W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular Power Supply, New Version with Build-in LED Fan On/Off Switch - Newegg.com
hec Zephyr MX 750 750W Peak Output ATX12V V2.3 / EPS12V V2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Newegg.com
You only require about 450W, however with that kind of processor I'd suggest getting a 750W. 600W is completely fine, however your system will run significantly fine with 600W. Go to: System Build - ************ put your parts in and the suggested wattage will be displayed.
