I went on the net since I was troubled by what I've heard and than wrote - that P35 doesn't support
real CrossFire/CF - well, wanted to recheck once again, just to be sure, don't like imprecise statements especially twice in a row, uncharacteristic for my own liking.
As you've probably seen, in the case of Gigabyte, it states that P35-DS4 does support CF:
see Gigabyte GA-P35-DS4 specs
Now, since I was sure about this not-so-real CF I reminded myself - check how much of a crossfire one can get if one port runs at x16 and another x 4 PCIe? Finally found the info that is clearer about it - people from the Xtreview explain the difference in data transmition through DMI interface in P35 (as it was in 965P) and the 975x saying why P35 allegedly fails compared to 975x - see this link :
INTEL P35 CROSSFIRE VS INTEL 975X
So, to be fair, CF is technically (but it may seem not that much "perfomingly") possible on p35 - so there is an actual CF and I wasn't 100% right
. Now, on the other hand, I am asking myself - was I that wrong though about the "actual" or "real" CF with this alleged under-performance?!
Would be interesting to see some test charts (fps wise) based on P35 with CF vs say 680i with SLi (and maybe 650i-sli and 975x) that would clarify this.
Anyway those who don't need CF should not worry I guess. Errr, me including. I think I am going for a DS4 this week :mrgreen:
