(Nearly)Every component of the rig I want to build is sorted. Aside from the RAM, I know I want DDR2 and for quite a while I've been thinking about OCZ's 4gb pc2 8000 reaper x
OCZ 4GB PC2-8000 C5 ReaperX HPC Enhanced Bandwidth (2x2GB) - Aria Technology costing £75.14 ($152.34 ). Then right next to it is 4gb of pc2 6400 reaper x at 800 mhz but with lower latency
OCZ 4GB PC2-6400 ReaperX HPC Enhanced Bandwidth (2x2GB) - Aria Technology, and it costs £84.54($171.39 . Which one should I get? Bearing in mind mushkins are very hard to get this side of the atlantic, are there any better ones I should get, or even 2gb of very fast ddr2 instead? Finally can my motherbord (asus p5q deluxe) support PC2 8000? Thanks for any help.
Edit: If I get 4gb will I need a 64 bit os?
