Hi,

Im thinking of getting a new video card, also might get vista and hopfully a duel boot with XP.
Im wondering if I went for a shader model 4 video card, are they backwards compatible with SM 3 or even SM 2?

Not sure what else I can ask. TY
I know it might be better to wait or whatever.

specs
Emachine T6522
3500+ AMD 2.20 512kb L2, 2k FSB.
1g ddr sdram
ati radeon xpress 200 (onboard)
about 250 watts PSU

Yes, the new DX10 cards that support shader model 4 also support 3 and 2. Just like the DX10 cards also have a form of DX9 that they run.


You will DEFINATELY need a new power supply. I believe 550w or 650w is the minimum but if you do decide to go with a 8800 GTS/GTX then get a decent 800w. If you want to go with the 8600 or one of the lower models, then you should be fine with 550w for a single one of those.

Theres no particular reason to get a Dx10 card right now. There really isnt any games that take much of an advantage of the new features. If your not in a hurry wait a few months or at least until OGL 3.0 comes out.
