I currently have a E8400 on an asus ip5 mobo with 4 gig Ddr800 ram and a ATI 4850 GPU. I'm not a big PC gamer at all. The only game i play is WoW. However, with my new purchase of a PS3, I am starting to get big into bluray movie rips. To do so, I use PS3 media server to transcode my blurray rips into the correct ps3 format. My e8400 def struggles a little bit to keep up. Will the upgrade to the i5 750 be a huge improvement? Or do i need to look at spending more money on an i7? Is 4 gigs of DDR3 suffiecient also? Thanks!
