I found this yesterday

And it looks like the 7970 out-performs all of nvidia's single GPU cards in about every game (I only checked Battlefield 3, Farcry 3 and Shogun 2). Which is confusing to me, because why don't nvidia just take their prices down, because they're just not worth the money.
Anyway, here is what my build is at the moment, and any recommendations are welcome (about a week until I can order this stuff):
Case :
BitFenix Ghost $120
CPU :
Intel Core i5 3570K $235
MoBo :
ASRock Z77 Extreme4 $135
RAM :
Corsair Vengeance 16GB (4x4GB) DDR3 Gold $115
GPU :
Sapphire Radeon HD7970 3GB OC Edition with Boost $420
CPU Cooler :
CoolerMaster Hyper 212 EVO $35
PSU :
Corsair CX-600M $100
SSD :
Samsung 840 Series 120GB $100
HDD :
Seagate Barracuda 1TB $75
Total: $1335 So probably too much.
I'm going with 16GB of RAM just because I use programs like Photoshop and 3D Modelling/Animation, so I thought it would come in handy. If I need to cut my build down though, this is the first thing coming down.
Another thing that will be coming down first off is the mobo, if I need to. Instead of getting the extreme series, I'll get a pro.
I like the case, looks like it's got good cable management, enough room, looks good, and it's silent. Enough cooling though? That's all I'm worried about. Plus great price compared to Corsairs 550D, which is pretty much the same. If I absolutely had to cut back on some more though, I would get an even cheaper case, seems as they don't affect performance.
I might be speaking blasphemy here, but is the AMD FX-4300 anywhere close to the Intel Core i5 3570K?
Last thing; would my 600W PSU be enough for my system listed above, without any of the cut-backs mentioned?
Thanks again guys for all your support and input for this build, I wouldn't know how to have done this without you guys.
EDIT: Actually, one more question; is there a big difference between the 7970 and 7950? If I absolutely had to downgrade something for $100 markdown, should I get either the FX-4300 or the 7950? Because they both knock off about $100, and the mobo cost would go down about $20-30 too if I chose to go with the FX-4300.
