Personally I haven't found them necessary. I too have a 7800gtx. With stock cooling, which covers the ram, they'd overclock to ~480 MHz; 430 MHz is stock.
"When I put a dangerden maze4 on there with no ramsinks, they overclocked to 515. YMMV and all that, and I haven't tried with ramsinks, but I still get 35 MHz more with nothing on them than with the original cooler.
i should of been more informative. Raising ram wont give u any increased performance until you hit around 650mhz on clock of your core. AFter that it shows more beneifital to raise ram speed in accordance to card speed.
There was a article about this on xs forums.
So if u havent done a volt mod.. then no u dont need those ram sinks. The Vin is right. If you did however volt mod, then your best putting those sinks on.
Personally id save up for a Koolsh NV-79 or NV78. I had 2 of those on XFX cards and gave them to my little brother as a xmas gift. But oh man, they hit 710mhz at almost 1970mhz on ram with a 1.5V mod and frankly those cards were NO JOKE.....
