After having 2 failed attempts at upgrading my graphics card with an x1950pro (both bought on eBay btw and where listed as "working perfectly, but I've upgraded to PCI-E so grab a bargin!") I'm putting forward this idea.
Upgrade my current ram from 1 to 2 Gigs of DDR400.
And upgrade my 256mb X800XL to a 256mb 7800gs (eVGA or XFX overclocked version).
Heres my current set-up:
Gigabyte K8NS Pro mobo (skt 754)
Kingmax Ram 1gig (2X512)
A64 3200+ CPU
Seagate 120GB HDD
600W Thermaltake Toughpower PSU
Would this be worth the dosh/effort to do so and will I see enough of an increase (fps-wise)to keep me going for the next 6 months or so. Bearing in mind I would love to have a crack at Crysis, Haze, Stalker-Clear Sky, etc.
Personally I think if you are planning on doing some upgrading in 6 months you are better of saving your money and going for the big time in 6 months. DDR RAM, AGP video cards and socket 939 CPU's cost so much that to replace them you will nearly spend enough money to get something modern.
I'm not completely sure about AGP but in PCI trim the 2600xt is about equal to the 7800gt which is better than the 7800gs. I'll be double checking all this in a minute but I'm pretty sure that this is good info.
