Nvidia GTS 450 SLI Help

[cadefoster]

Hi,
I just picked up The Witcher 2 and my current gts 450 just dosn't cut it, at least at my resolution of 1920x1080. I am thinking of picking up a second 450 to run sli. I have not run sli before so I could use a little advice. Right now I have the msi cyclone 450, is it a good idead to pair the excat same cards or will any gts 450 work the same? Also, how much of an isue will heat become? should I add more fans to the case? Thanks to anyone who can help.

hi, the witcher 2 is very much demanding game.Many high end PCs have trouble running it but i think i should tell you that your Fps will improve if you'll uninstall the 3D drivers in you gpu and turning the Ubersampling off.Although if you want to updrage your graphics performance you should replace you 450GTS with some 570or580GTX. you'll see a much larger performance boast.
