Redmoon, I doubt you will be able to play games like Crysis and COD 4 on low settings. I recently sold all 4 of my 3870's before the price went down with the release of the 4850 and 4870. I just bought a 3850 for £28 on ebay. It is just temporary until the 4850 and 4870's have oc editions with better cooling and more memory. I believe the 3850 will struggle to play games and that is twice as fast a 8600gts and probably 10 times as fast as yours.
