HD 4890 Black Edition or GTX 275 OCX?

[crazyguy_60]

I'm not sure whether to get the 4890 BE or the 275 OCX (in case some of you are not aware of the OCX, it is clocked about 35Mhz HIGHER than EVGA's SSC version (709Mhz vs 674Mhz), and is only £9 more than the HD 4890 black)..
I almost defo will be adding another one. If I get the GTX 275 OCX's, I will have to get Core i7 as there are currently no AM3 SLI boards, and I don't want to use an AM2+ motherboard because backwards compatabilty reduces performance. If I get the 4890's I will get AMD Phenom II X4 955. However I would rather get the AMD setup because its cheaper.. But it soley depends on the graphics cards.
I couldn't find any review on the GTX 275 OCX, but some review say that the 4890 BE ban outperform the GTX 285 in some tests.

Thanks!

I'd get the 275.http://www.bjorn3d.com/read.php?cID=1554&pageID=6778

I'd look very, very carefully into the motherboard/case first.
Either of those combinations is going to produce a lot of heat and most motherboards do not seperate the cards enough to allow the upper card to get enough cooling air and the last thing an overclocked card needs is to have its cooling system choked.
As for cards: I like the GTX275.

they trade blows, and that's only the OC, which is clocked 60mhz lower than the OCX.. however that means I will need to buy core i7..

What about SLi & CF?, that's more what I'm interested in seeing.

GTX275 OCX = bad.... way too hot and it seems they didnt up the voltage enough to counter the higher core clock speeds.

Went thru "3" of them thru BFG Support before they finally sent me a GTX 285 as a replacement for my troubles.

GTX275's are great cards if you keep them under 690Mhz. Anything higher then that and they get WAY too hot and not that stable.

All of mine were going above 90*C and thats WITH a VGA cooler and a front fan blowing directly into the cards front intake.
