Well I'm building a new pc next weekend and was wondering if I should pick up a 9800 GX2 for 259 or the ATI Radeon HD 4870 by Sapphire for around the same price. Using the Corsair 750w TX PSU, will it cover the needs for both of these cards along with an OC'd Q6600/Q9550 (not sure which yet)? Which card performs better, if the nvidia card which mobo should I get?

The 9800 GX2 has more Power than the 4870, while the ATI card has less problems because its single GPU, Atleast thats what most ppl would say:) 

I for 1 will say GX2 since the price is perfect, and from personal experience I don't have problem with a single GX2 or even dual GX2s when it comes to game performance.

The only thing the 4870 has going for it, is that it runs 55nm and DX10.1...thats not to say its bad cards.

Either way at the same price range I think the GX2 is the better buy.

Although at the plus side, the 4870 could be paired up with a 4870 X2 :)  althought I don't think it would beat the GX2 in Quad sli, it would still be pretty awesome:D

I agree with you L1qu1d. Been having some problems finding benchs for this particular situation on (basically) the same system. Seems to always be a completely different system between the ati and nvidia benchs. Any ideas on what a good mobo would be to get with the 9800 Gx2, comparable to the Asus P5Q pro (P45) mobo.

LOL well I've only had Asus Mobos, but they are also ridiculously overpriced:)  (in most cases)

Personally I liked the the Asus Striker II Formula, but I'd have to say that the EVGA 132-CK-NF78-A1 3-Way SLI Socket 775

But either way I like high end:p  I stayed away from DDR3 because thats TOOOO high end, but you might want that:)

Too expensive for my budget with that motherboard. Can anyone else attest to the difference between a 4870 and a BFG 9800x2 card on a ~150 motherboard.

Well the GX2 ran well on my Asus M2N-Deleuxe 570a :)  that board only cost me around 70$:D s

9800GX2 :)

One question that can give you the answer: how do you feel about AA? In fraw power, the 9800GX2 tends to be higher, and hence tends to do better at very high resolutions... But AA really saps its performance, yet AA hardly dents it for the 4870. If AA is off, the 9800GX2 is better.If you need your AA, (some do, some don't; personally I prefer it over higher resolutions or HDR if I must make a choice) then the 4870 is the right choice. Just also remember that the 9800GX2 takes some half again as much power, though with that PSU you should be fine.
August 22, 2008 1:41:45 PM

actually the GX2 still beats the 4870 with AA on ( I don't know about 2560 resolution) but at 1920x1200 and lower it holds it's own:)

It wins in a couple of cases, though in several of those, the results are somewhat irrelevant; at the points in Crysis where I see it win, it's unplayable anyway. (though weirdly enough, the 4870 can run the game outright maxed for 4 fps, while the GX2 can't run it at all) Whereas in titles like Test Drive Unlimited and World in Conflict, the 9800GX2 takes a significant beating at multiple resolutions once AA is brought on board.

But yeah, also, it seems pretty consistent that at 2560x1600 with x4 AA, the 4870 almost always trumps the 9800GX2, which actually I'll admit seems a tad strange to me.

Supposedly DX10.1 games and software is comming out this fall, end of this year. I think Nvidia is dumping as quick as possable. The 9800GX2 was 600.00 just a few months ago. Nvidia knows something and are not telling anyone.

Yes it does In Conflict but in cases it becomes unplayable:D

That they supposedly have a "killer card" they're holding back? That's not gonna happen anytime soon, sorry. If they had it, they would've actually benefited from releasing it as soon as possible, as every day the 4800 series is out against nVidia's lineup is one that they lose both profit margin and market share, and all they can do is control which they lose more of.

The short story is, what nVidia knows, and most of US who pay a lot of attention know, is that they have nothing to offer in competition as far as new cards go, and they've decided to sacrifice profits. Yes, their cards were previously sold at a pretty good profit; it certainly didn't cost them anywhere near $600US to make a 9800GX2, but because of its vaunted crown, it could command that price. But now that it doesn't, they've got lots of those GPUs to move, and thus they've slashed prices hard. I wouldn't be surprised that if in a few cases, they're actually losing money on some cards, namely the GTX 200 series.

No, nVidia HAD their "killer card;" it was called the GTX 280. But they already expended their one shot, putting forth all the resources they could muster for pretty much all of 2008 into that one launch, and it turned out to be an utter dud. They gambled big time, and lost, so now, they're just in the stage of damage control until at least 2009, when they have a possible chance to get back into the game.

It's possible they might, though perhaps not immediately. I liken the 4800 & GTX 200 matchup as like a re-play of the 9700pro & GeForce FX matchup. But in that case, again it wasn't fatal to nVidia; they did make it back, and less than two years later, they were back in full competition, making good high-end inroads with the 6800 GT, which provided excellent price-performance numbers even though the 6800 ultra couldn't budge the performance crown from the plain X800XT, let alone the X850s and PEs. The real news for nVidia came from massively dominating the mid-range market with what was one of their best-selling card ever, the GeForce 6600 GT.

Well, given that it's an RTT and not an FPS, a minimum of 30 fps is not a requirement... The 15-20 fps range could be considered playable, provided its mildly consistent.
August 22, 2008 5:12:36 PM

yes its an RTT, but it is still annoing to play under 30:) 

Either way the Average games:

Crysis:



COD4:



Even now that I see world in Conflict, the GX2 has an advantage as well:)

Remember this is the 4870 not the X2:)  it has 512 megs just like the GX2

Well I'll be getting a 24" monitor on the egg for $250 resolution will be 1920 x 1200 correct? If so they seem to be pretty similar. Can anyone look up some more bench marks for different games? (oblivion, tf2, crysis are what I play atm but will be getting some new games I'm sure to put this baby into more games)

It seems 3DMark06 gives the 9800 gx2 a 57 higher score. 9800gx2=12992 4870=12935.
August 22, 2008 5:56:02 PM

TF2 isn't demanding at all, my dad's 8400 GS and my gf 3470 can do it:)  Obvlivion has problems with the GX2 in sli, I dunno if single anymore.
I never liked the game so I never played it.

Crysis benchmarks above
August 22, 2008 6:14:29 PM

Yeah, my current rig can handle tf2 pretty well. Average fps is probably 50. Just trying to get the best performance for my money. Toms review has the 9800 gx2 ahead in all of it's games...

Mass effect: 9800gx2 by 10 fps with AA on. .2 fps with it off.
COD4: 9800 gx2 ahead by 20 fps with it off, 9 with on.
Crysis: 9800 gx2 10 with off, 1 if on.
UT3: 9800 gx2 20 on, 20 off
August 22, 2008 8:39:26 PM

What would be the minimum power supply needed for a single 9800gx2 core2duo system? These cards seem like a steal right now, and I'm not interested in ever SLI'ing or crossfire'ing cards.
August 22, 2008 8:48:46 PM

I would get the corsair 750w tx since it's only going to be like 10-20 more than what you need, but much better quality. Maybe the gamexstream 700w psu for $20 less.

So can anyone tell me a good motherboard for the 9800 gx2 graphics card?

Chipset wise, me thinks any P45 should do the trick or a nv790 series wich has proven to be very close to the P45 in recent reviews (TH has it all, lol), but don't know 'bout prices. If u're not thinking bout QSLi, even a single lane X16 is good enough. Keep in mind that nVidia is gonna pop his new cards in a couple of months (was it Q1 2009?) and you can upgrade then.

I kinda like Asus and DFI, but i can't say Gigabyte, MSI and a lot of others don't make great MoBos. Look for the "goodies" they offer and choose according to that.

Esop!
August 22, 2008 10:02:28 PM

Thanks, I think I'll go with the P5Q pro and a 4870. I mean it's not a huge difference in fps and crossfirex will probably be better down the road, plus AA handles better on the 4870 and it has 10.1 directx...
