Ok...both of these I'm lookin at have 512 MB, 256-bit processing (actually there's a 512, 512 2900PRO)

Wouldn't they have the same performance...they're both GDDR3 too?

Confused

It should be about same performance except that 3850 would be whole lot better in power consumption, has dx10.1, and possibly better AA performance.

The HD2900PRO 256bit only has a single 8pin power connector not two like the 512bit, do you think it's still power hungry over the HD3850? I guess it only has a 6pin connnector and a heatsink only model so It's a better bet if you don't have a problem with PCI-E 2.0.

yeah, it will draw a lot more power than the 3850. The 3850 is based on a 55nm process.

Go for the 512 3850.

Or a 512-bit 2900 PRO if you can find one (and if you don't mind the power consumption).

Well I actually have the 2900 Pro 256-bit and I'm able to hi 11k in 3dmark06 with my OC using only a 6-pin adapter. I just ordered a 3850 512mb card, and it should be here by Monday. I'm going to do a full comparison of both cards. as soon as it comes in. I'm hoping that I can achieve better performance with the 3850 512Mb when OC'd versus the 2900 Pro OC'd.

If you want to wait, I'll post my results, that way you can know which one for sure is better.

If it's not from Yorkshire it's sh1te

43c, fan at 39%, which is still inaudiable for me. Tomorrow I'll have the 3850 512mb, so I'll be able to show you guys which one is better, I'm hoping on the 3850 512mb, because it cost me more money.
