I saw that too this morning and thought the 9800GTX+ in SLI would actually be a better deal (assuming you have an SLI board). I've seen those cards go for as little as $120AR (like the one in my rig) and a pair of them will kick any single GPU setup at 1920x1200 and below, with one exception - FarCry 2 at Ultra High settings, where the 9800GTX+ stumbles.

If you tally up the performance (1920x1200):
SLI 9800GTX+ vs singleGPU - Wins 6 out of 7 benchmarks (convincingly in many cases)
SLI 9800GTX+ vs 4850X2 - Wins 5 ouf of 7 benchmarks (but uses more power)

Great article... most of all I appreciate they included the 9800GX2 which has disappeared from a lot of GPU reviews lately...

I obviously overpaid for this card but I appreciate seeing that it's still quite competitive with today's latest, and I'm more than satisfied with my card's performance in 1680x1050 resolution.

That was a nice article. Anyone know why the Xfired 512MB 4870s generally performed better than the 4870X2?

?? It looks like the other way around in most of the games. Which would make sense, as the X2 should have a bit of an edge with a dedicated interconnect between the GPUs.

Do they have 1GB 9800GTXs? That would make more sense than putting 2x512 versions in SLI.

Hmm. I guess I shouldn't have used the word "generally". But GRID@1920x1200, L4D@all resolutions, Crysis@all resolutions, and COD5@1680x1050 & 1920x1200 show the Xfire solution ahead of the X2. Some of the results could be attributed to margin of error but still looked kinda weird to me since the X2 has the dedicated interconnect as you mentioned.

There's also the shared PCIE bandwidth to consider, which was also pretty evident when comparing 1GB 4870 CF and 4870X2 in some earlier reviews.

9800GTX+ 1GB Review
Its actually enough difference that it overtakes the 512MB 4870 in some games and resolutions, but still clearly slower than the 260 and 1GB 4870. The problem is pricing, if its $160-180 it'll compete with the 512MB 4870 which still beats it in most games. If its more than that, there's the 260 and 1GB 4870. Maybe an interesting if its $150 or less.

Overall Derek did a really nice job with this review, although there's some things I'd like to see added or followed up on. Looking forward to the rest of the articles they're prepping for sure.

are they hinting at new cards coming out soon?

Im guessing these are the rebranded GTS series cards from nVIDIA (GTS240/250) and maybe the rumoured HD4700 series (RV740) from ATi.

edit - nice article by AT, would've been nice if the partners or AMD themselves pushed the HD4850X2 SKU instead of it being a custom made solution.

I think he literally means three cards on the board. As in tri-SLI, FrankenFire, etc.

Or this. But Triple SLi costs so much I doubt it would change any landscape.

I'm guessing he means, "let's see how adding a third card changes the performance equation". Just speculation though :D.

If he were hinting at upcoming products, I tend to think that he'd say "stay tuned to see how three cards will change the landscape".

Great article. I'm glad for the state of the multiple gpu nation address. Looking forward to the tri and quad setups. Prediction- still not worth it! anybody want to go 2:1 on it?

I wondered about that possibility but I thought that modern graphics cards were still a ways off from saturating a PCI-E 2.0 x16 slot.
