On the verge of buying/putting this together..

1TB HDD
8GB RAM
Corsair 500R Case
Antec Series HCG-620M 620W PSU
GTX 660ti
i5 3570K
Noctua NH-U12P CPU cooler
GIGABYTE GA-Z77X-UD3H mobo

Total = ~$1200

I've been meaning to buy a rig for awhile and was about to buy one about six months ago after help from this forum, but backed out. Now I'm ready to actually spend some cash but decided to revise the build and this is what I've come up with. Is there anything that stands out that should be swapped? I want performance without going overkill, though I could spend a bit more if worthwhile. Any tips/recommendations or thoughts on this build would be much appreciated. I don't know too much about PC gaming and therefore not much idea on how this rig would perform under the weight of more demanding games.

Thanks.

swap the 660ti for a 7950 or a 7950 boost (both are the same price) after that you;re good to go.

I've read a few articles now on how the GTX 660 ti edges the 7950, though the difference is minimal? The store I was ordering from doesn't have the 7950 listed either.

Also, I edited my first post; I'm thinking a Corsair 500R would be a more appropriate choice than the Storm Trooper, and I forgot to add a CPU cooler. Does anyone know if a Noctua NH-U12P would fit into a 500R case? It might be an obvious question, but I know very little about it all so I'd have no idea. Would the stock fans on the 500R be fine for general gaming? Oh, and does anyone know much about dust filters, and would recommend them?

7950>660ti.

no, the 7950 smokes the 660ti. Also you should get an SSD.
