At the moment I am running 2GB (DDR-800) of RAM in single channel mode (two chips but different brands so MB doesn't recognise it as dual) on the following set up:
Win XP 32 bit
Radeon 4670 512 MB
Is it worth me forking out $120 Aus for two x 2 gig chips (4 gigs in total, although I know XP will only see 3.25 gig of it) that can run in dual channel mode and I have more RAM? Or would my money be better spent on a new video card or maybe CPU?
I only use my PC's high end capabilities for gaming.
Well DDR2 RAM is very pricey now I would say its not worth touching that system your processor is too slow for modern games and the 4670 isn't the best gaming card either. I would wait til you have enough money together to do a full rebuild since all your components are a tad out of date.
