Ok here are current specs:
Cooler Master Hyper N520 cpu cooler
q9400 2.5 ghz cpu
evga 9800 gt
XFX nForce 750i SLI Extreme Edition mobo
thermaltake v9 case
6gb ram ddr2
Ultra LSP750 750w Power Supply
vista 32bit (but i will change it to 64bit i just couldn't find my 64bit last time i installed os and i don't know if windows 7 works on mobo)
So i'm thinking of upgrading gpu and i am sick of dropped frame rates so i will go overkill. I was thinking gtx 460 in sli or something like that. my price limit is $400. First can my power supply handle 2 gtx 460s? and here are 2 gtx 460s i am debating between which is better?

then there is 20 off coupon with each
Oh and how much would these cards be bottlenecked and is it worth it?
