I would NOT reccomend for vista over 4Gig of Memory MAX! For windows probably 2-4Gig is a bit of an an overkill.... If your using that much Memory you have a problem.. What are you running like three or four world of war craft windows... But still your cpu is a huge thing.. If you have the cash for 8Gigs of Memory why not spend the spare cash on a quad core 3Ghz Pentium 4 processor? that would own your 8Gigs of memory on your Dual Core processor.. Lols.. Also upgrade your Mobo alot more too, If you have enough cash for 8Gig of memory i'm saying that you must have enough for a better Mobo and processor.. Plus it's probably DDR1 RAM or something lol.. If you want me to explain more in detail post back here... Great reviews guys i'll be updating soon with better pictures etc.. I'm hoping for a sticky so all the people know what were talking about with mobo's, memory etc.. On the other hand i'll be coding a new website completely dedicated to you Techies out there.. So if your interested drop me a Pm, This site will have alot of mods etc so i can code without moderating the forum.. I expect you all to be mature. EDIT: using invision and going to skin it myself etc.. So url is.. Here! Join for more help! Thanks, Justin.
