I don't think I could pump it to any higher resolutions, but my monitor only goes up to 1280x1024 anyway.
i only have a 2x ATI Radeon HD 4870 on Crossfire 512MB DDR3 cards.and a Dual Core cpu 2.7 each.
well I wouldnt even say a 2.4 ghz because I run it on max settings with a 2.19 and a nvidia 9600 gt with 3698 megs of ram
are you firing on a single core 2.19? a dual or quad at the same ghz level will outperform a single core.
