I posted this over at Anand but have not gotten any satisfying responses yet. Newegg has two different EVGA 7800GT's for sale.

GDDR2 version http://www.newegg.com/Product/Product.asp?Item=N82E16814130247

GDDR3 version http://www.newegg.com/Product/Product.asp?Item=N82E16814130238

Both have same core clock (445) and memory clock (1070). As best I can tell the only difference it one uses GDDR2 and the other GDDR3. Does the GDDR3 version really worth the $80 difference? What would be the difference in real world benchmarks? If there is a real world difference, to me this is like when video card makers sell 128bit memory interface cards at reduced prices compared to 256bit cards and fool the uneducated customer.

I just got the "DDR2" version yesterday, and it has DDR3 on the front of the box I got. I am not sure what the difference is between the part numbers. The one I got is 515 and the more exspensive one is 518. I dont see a difference. I am REALLY happy with what I got! :)

If they are clocked the same I don't think you would notice a difference.

I believe DDR3 works at lower voltages, so if your looking for a good overclock, go with the DDR3, however, I don't think there will be any performance differences...

I really think this is a typo by Newegg. I also wonder about the MSI card they have listed there. All the Manufacturers links they have lead to a 256mb card, but the listing says a 128mb card.

It is definately a typo at NewEgg

All EVGA 7800GT's have DDR3

I'm waiting for the first posts about "I fried my 7800 GT overclocking" !

Very clever move making these babies in need of less power, GDDR3 3 ram too? wOOt
I should get mine tomorrow and I cannot wait, overclocking time here comes.
First one to blow theirs up, gets the empty box for mine in consolation, 470 / 1200 seems to be the limit so far, any beaters?

Yep, alot of the 6800 GTs used GDDR2 , pretty certain of that.
And especially all the 6800LEs.

GT's used gddr3 just like the ultra's, while the regular 6800's used ddr.
