I am saying that obviously they will be DX10 compatible, since neither SLI nor Crossfire depends on the DX version ran. If the individual cards run DX10, then they can be Crossfired or SLI-ed.
Here are some benchies:
- 3DMark05: Crossfire X1950's at any resolution
- Prey: QUAD SLI (Dual 7950GX2's) at any resolution; at high res with AA/AF, Crossfire X1950's is very close though
- Half-Life2: Loast Coast: Crossfire X1950's, Crossfire X1900's, and SLI 7900GTX's are all close, except at highest resolution with AA/AF where Crossfire X1950's pulls away. QUAD SLI lags behind here.
- Call of Duty 2: Crossfire X1950's at any resolution
- F.E.A.R.: SLI 7900GTX's at low res, Crossfire X1950's at medium res, QUAD SLI at high res, Crossfire X1950's at high res with AA/AF
Thus, when you turn on the eyecandy (AA/AF), Crossfire X1950's pulls away
Here is more:
And this I think is what really matters:
As we mentioned on page 2, we excluded the Quad SLI config from most of our 4xAA testing simply because we already know that it underperforms in these situations against a GeForce 7900 GTX SLI rig, so of course it can’t hold an even halfway decent fight against a pair of Radeon X1950 XTX cards running in CrossFire mode. The GeForce 7950 GX2 is truly built to run in one environment – NVIDIA’s Super AA modes – and anyone who buys a Quad SLI rig to game at 4xAA/16xAF and/or low screen resolutions is simply wasting their time and money. Quake 4 and F.E.A.R. were the only apps we tested with today that run well at 4xAA, and as you saw on pages 6 and 7, the Quad SLI cards perform well there.
Despite the strength of ATI’s compositing engine, four G71 GPUs running in sync with each other is too much for the Radeon X1950 XTX CrossFire board to overcome, NVIDIA’s GeForce 7950 GX2 Quad SLI setup is the clear winner at 8xAA. But the tables quickly turn once you crank up the AA.
Once we turn up the AA levels to 14x for the ATI cards and 16x for the NVIDIA cards, the performance edge shifts dramatically in ATI’s favor.
Thus, who'se the winner? you tell me
Depends on settings, etc, and what preferences you have.
