Does it look okay? compatible? You know, will it run a game like ACIII or far cry 3 on high or even ultra?

And what of the sound card? will I have any compatability issues with my old one?

Looking good, but PSU too powerful max you would need 620w psu
And go for second gpu, vaporx one

Thanks for the reply mate, I'm thinking of getting this GPU instead.

Would that fix both problems?

And about the RAM.
Would this one be better? http://www.amazon.com/Corsair-Vengeance-240-Pin-Platforms-CMZ8GX3M2A1600C9/dp/B004CRSM4I/ref=sr_1_1?s=pc&ie=UTF8&qid=1355358450&sr=1-1&keywords=Corsair+8GB
