Test if your PC can run GTA IV

[Hitman]

just because of my stated CrossFire/SLI disadvantages, which you dont have with one single gpu.

believe me, 2-frame-lag is shitty, i used an 3870X2 and 9800GX2 myself, both are crappy.

-just 512MB vram (no, 2*512MB is 512MB in SLI. You dont have 1GB, because every GPU has to render the same frame)
- heat (2 cards will be so fuckin hot that your whole pc is hot
- power consumption (2 cards need incredible power sources)
- micro stutter (every gpu renders the same frame, and they send this frame to your monitor to show them. but now one gpu is a bit faster in rendering that frame than the other, but both send the same frame to your monitor. this causes lag, and sometimes the lag is so big that your game doesnt run smooth, although it shows like 60FPS)
- alot of games have no SLI-support, and runs like you have just 1 graphics card

The same counts for CrossFire ofcourse. And the micro-stutter and 2frame-lag of dual-gpu cards suck, trust me. Sometimes you have this feeling that your game doesnt run smooth all the time, you turn fraps on: all the time over 40FPS and you are like WTF?

Just trust me, i used both alot (radeon X2, nvidia GX2 and single gpu cards), and i modified all my games with the programm "nHancer" to make them SLI or CF compatible, but still - it sucks. 60 dualcard FPS arent as much worth as 60FPS with a single_GPU card.
