ok that is a great choice, nice work staying away from home basic and 32 bit (its alright but 64's faster surprisingly) and i recommend you stay with that case and cpu the thermal take is probably one of the best brands and the quad core, oh my god i love mine!!! i have a q6600 it is GREAT I absolutely adore it it is great!!! also the 2 gtx's in sli is a great idea, that will substantially increase performance in resource hungry games ergo crysis i also envy the fact you have a motherboard that supports PCI-E let alone sli, btw im still on agp, and no im not lying about the quad i also envy you getting the higher end quad core. anyway leave it at that i cant see any other improvements well actually just a thought but people get good frames in crysis with one 8800gt 512 so maybe swapping them for 1gb 8800gt, that would make the ultimate system the gt is all owning and try to stay away from all current 9800 right now their performance is not as good as promised and they cost way to much
