Nope, I didn't mean 'limited' in the sense of 'cut down from a higher-end part'. I was waxing mildly philosophical about whether or not the entire R600 design had an optimal ratio of shaders to texture/ROPs.
So, yes I know that the 2900pro is just an underclocked XT. Thanks for asking for clarification, however!
Cheers.
ronnn - I imagine that SickBeast meant that playing Crysis at a level of performance, resolution and eye-candy acceptable to the gaming enthusiast would require something very, very powerful.
I'm sure that quality settings in Crysis will allow for a lot of hardware to work and SickBeast knows that. Heck, I'm sure my x850xt will run it in DX9 mode. Now how well it will run it, I just can't say...
SickBeast - I tend to agree, though I think that the R600 just turned out to be a bad architectural decision: lots of shaders, but trouble keeping them fed, no hardware AA, etc. It's almost like ATI made some bad guesses about what games would require right now, when they started developing R600. In the end, if Nvidia is really just standing pat, ATI will eventually make them pay...or, given the track record of AMD, maybe they won't...

At last, a bit of decent competition from ATI in the marketplace.
Finally Nvidia's stagnant pricing and lack of innovation will have to change, and this can only be good for the consumer.
I've noticed that on certain sites in the UK that the regular 8800 GTS 320mb has dropped about £10-£12 already, but is still more expensive than the 2900 Pro, which can be had for £170.
Seems we have a winner from ATI!

The Pro does look good. I'm willing to buy it if it drops below $240 or so. The big thing for me is low power consumption - I know I need to get a new PSU, but being able to feel comfortable on a $60 PSU instead of a $100 one is nice.
They should be close to twice as fast.
You're right in that there may well be a 'stumbling block'. The GPUs of late have been very hot and power hungry. They could be hitting the same wall that CPUs hit not that long ago.
I don't think any of this has to do with DX10. The reason there haven't been any faster cards is simply because AMD has not offered competition, so really nVidia will remain top dog until someone de-thrones them (and they can continue to sell GTX's for $$$).

this year is the battle of the mid-range
i need to CrossFire to get any more performance

I think that russiansensation got his hx520 for $70, that's probably more than you'll ever need and a fantastic deal to boot!

Yes I did. It was a $20 mail in rebate and $10 Googlecheck out off $99.99 with free shipping at Buy.com. There are always deals on power supplies around (doesn't have to be the best) but good enough for a mid-upper range system today like this 650 Watt Cooler Master for $40 + $10 shipping (2x 18A 12V rails)
Hrmm.. there's a lot of people saying they'll buy one of these to X-fire with their 2900XT....
Will that even work?? I know they're both "2900"'s... but still.. one's slower than the other..

that is *me* - i started this
Who knows for sure? ... i am willing to risk a restocking fee to try it
i know 2900Pro and XT "works" together with the latest X-fire.
My reasoning is this:
My HD2900xt runs at full speed in the 16xPCIe slot ... but my 2nd slot is a 4X PCIe slot so the bandwidth is slightly limited; i am guessing that a slightly slower card in the 4x slot should be fine
--worst comes to worst, i will OC the pro a bit to match the XT's speed more closely
---actually *worst case* is not finding one for MSRP or less

Won't the fast card in the x16 slot have to slow down to the slower card? Granted, performance "should" be better than a single 2900XT, but will it be 250.00 better?
I guess we'll see.

yes, it runs at the pro speeds ... OC'd pro speeds which should be marginally slower then stock XT speeds [which would be held back slightly by the 4x slot anywayOriginally posted by: keysplayr2003

"Worth $250?" ... as i said ... who knows for sure? ... yet
- it will be worth $40 to find out [worst case return or sell it]
i KNOW it is not worth $360-400 to me to get another XT
- and i definitely AM considering waiting for the XT to drop in price
decisions ... decisions ...
FIRST, i have to find one at MSRP or less

no matter how you look at it, it is still much faster then a single 2900XT
worth $250 faster?
unsure
[especially since i am playing at only 16x10 ... but i want *all* the "DX10 crap"]

still looking. I haven't found anything yet that discusses how to run xfire with 2 cards of different speed. This situation could also come up with 2 identical cards that have different overclocks on them, too.

AMD made it possible to use different cards together in xfire with x1950 series ... they DO default to the lower GPU's clock speeds
... and it looks complicated OCing in xfire:

so you would get the 2900pro, then try to oc it to xt levels so that it would slow down your 2900xt on the 16x pci-e slot...hmmm...

If he doesn't, or can't, o/c the pro, then the XT will slow down to the pro speed in Xfire.
If he is able to o/c the pro to XT speeds, then the XT will not have to slow down at all.
BUT, the pro has 600MHz core and the XT has 740? or 800? I forget. Anyways, that would be a sinch if the pro cores aren't from a poor yield batch and not undervolted.

it wouldn't slow it down at all ... IF it were the same clock
my XT is at 743mhz i think ... if i could get the pro up to 743Mhz the XT would run it its rated speed and the pro would just be somewhat bandwidth limited by the 4x slot
if it were much slower ... say stuck at stock pro speeds ... well then, there goes $40 in restocking fees.

I'm still steamed that I never could benchmark my ip35pro vs my buddies' msi 975x in xfire to compare. You'd think that he would take better care of his xfire bridge...
