Which is better?

[Graham]

I can run Rainbow 6 Vegas, Ghost Recon Advanced Warfighter, Supreme Commander, BF 2142, FEAR, HL2 Episode 1, Quake IV, Prey, etc on full blast with no let down with my system at 1680x1050 on my sweet dell 21" widescreen = )

Screw the SLI. Save the money for a vid card upgrade when Crysis and other system killers come out.
