Will they ( Athlon 64 boards) run DDR333, PC2700, because if I did go the Athlon 64 route I'd see about using it as a replacement for this system, but would like to use my existing 512MB DDR333, the other stuff in my system is no prob, vid card, sound card, etc. but need to know if older ram will work (even though its running slower than the fsb of the board), also will WINXP Home be able to support the 64 or would I HAVE to upgrade to XP PRO, not should I, but would I have to?
I have to take all this into account as I might need to buy more RAM, possibly a new OS, definetally need a better vid card, gonna get one of those newer 36GB Raptors, & add the Board & CPU into the picture & I could be spending a lot more than I want to!!!
My original plan was to upgrade my current system to a newer KT600 board or nForce2 Ultra board get a new Barton 2500+, add a 512MB stick to my existing 2x256MB sticks for a Gig, Buy the Raptor & get a new GFFX 5900XT, 5800, 5800U, 5900, or 5900U 128MB or 256MB card (yeah i know the 256MB cards are a bit slower, but their 256bit memory & still blazing fast compared to my existing GF4Ti & GFFX5200 cards), which ever I can get the better deal on, & also see about getting a new CRT, 17" or 19". But then decided to see about just getting a new vid card, more RAM, & the Raptor drive (plus a SATA Card) for now & if I still need more performance then I would see about a new board & CPU, but then just recently heard about the "Thorton" chips & now want to possibly add a new CPU into the equation too.
The thing is, is that I'm pretty much stuck on what to do, I want a 64 system, but don't want to spend too much cash & still want to keep my old one too, but also wouldn't mind severely upgrading the existing system instead of getting a 64 system. I can't afford a FX51 system, & wouldn't mind settling for a basic 64, but not sure how it compares with gaming compared to say the top of the line Socket A systems with the Barton 3200+ chips in it.
