Wondering if I should upgrade mostly for gaming and some programming. Now Ive read a lot of opinions, and people are right that most games use 2gigs tops... But it seems to me windows caches more to hdd with 4 gigs, and correct me if I'm wrong but my gtx 460 will borrow ram if it needs it. Anyway, I'm sure someone here can address my concerns. Oh by the way I game at 1080p.
