8600GT 512MB or 8600GT 256MB

Guys please tell me i cant decide.
should i go for the Nvidia geforce 8600GT 512MB(GDDR2)
or
the evga geforce 8600 GT 256MB(GDDR3)

im planning to SLI two cards which should i go to??
one has a 256MB memory but has a ddr3
the other has a 512MB but has ddr2


pls help

Like i said should i get the 8600GT that has 512 MB but runs on ddr2 or should i get the 8600GT that has 256MB that runs on ddr3.

and that too im looking to sli the two cards . what should i get??
2 of which one??

pls help

The one with 256 MiB of GDDR3. 8600 GT doesn't have enough power to utilise 512 MiB.

Instead of SLI , why dont you buy the 8800GT.
I think it will more or less match the performance(even better it) of 2 X 8600GT (512,256 wont matter much).
If you are looking to buy a single card then check the price difference,although i think 256MB of GDDR3 would be better than 512 MB of DDR2

@sahitanand Please dont create multiple threads.
Merged the two threads for you this time !

im sorry..
i could not find my previous thread so i thought i forgot to submit it after ytping and all hehehe my bad wont happen again sorry.

anyway the price difference isnt much at all..... im gonna run my q6600 on 3.5Ghz so itnt it better to buy two 8600GT 512 MB(ddr2) ?

and one more thing say i buy the 8600GT 256MB(ddr3) and SLI two of them, will it beat the performance of the 8800GT?? or any other card of 512MB on GDDR3??

Oh yeah asky the 8800GT is Rs.15000 while 2 of any 8600GT wont go more than Rs11000

One 8800GT is faster than two of those. And 8600GT with 256 MiB of DDR3 is faster than 8600GT with 512 MiB od DDR2.

For the price - a single 8800GT is going to be your best bet. The hard part is finding one, tho..

Indeed. A single 8800 GT will be a better solution for you. Theoretically, it should be equal or greater performance than SLI'd 8600s. Also, a single card will draw less power, create less heat. Hope this helps!

Yeah one 8800GT would be the best option. I got one from Dell for $207 ($222 shipping/tax) too bad they're telling me its delayed until Jan.
