absolutely none - a vMod just makes your card overclock higher, to experience the improvement you WILL have to overclock it!

^^lol im aware of that, i was just asking once you volt mod it and overclock it to say 650mhz is there a significant performance increase in FPS??....that was my question...i already knew that it would have to be overclocked and that it would be overclocked higher on a vmod.....thanks in advance

From my testing the largest performance increase is from the GPU core, raising the memory frequency gains a bit of performance but the core is where the huge leaps are made. Plus raising your memory too high is half the time the reason for artifacting.

If i volt mod i'll be only concerned with raising the core, i'm already 100Mhz higher than stock, and that 100Mhz gain makes quite a difference in average frame rate

From 450 to 650 you would see a very discernible difference, I would imagine about 15-20 fps easy. As for the cooling, I think it will take up the slot adjacent to it, but I honestly dont remember, been a while since I owned that card.

haha thats what i was hoping for!...hehe....i cant wait to get this stuff so i can volt mod....i just didnt want to take the risk if it the performance gain wasnt worth it but i hear that it is worth it

Wrong, that would be the Thermalright HR-03. But the VF900 is great.

Well if i volt modded my card, i'd jump passed the 10,000 barrier in 3DMark05 and that's with one GPU, if i had two volt modded 7900GT's it would be 3D Heaven

i think i posted this already but just in case.....i know someone was asking for a pencil mod for the 7900gt....seems you can only do it on the RAM but here is the link again explaining mods for the ram and GPU....i did learn that if you can run the voltage at 1.55v you can probably hit around 700+mhz on the clock speeds....its already been proven to hit 720 with the extra .1 on the voltage...im gonna try the 1.4 then jump to a 1.5 if im not satisfied after i get my cooling....heres the link just in case i didnt send it http://forums.anandtech.com/messagev...&enterthread=y

and here is the mod for 700+mhz on the clocks...definitely check this out! http://www.xtremesystems.org/forums/...ad.php?t=94177

I won't add to the accolades...

But simply, "Yes"

7900GT w/ 1.49V + VF900 = 670/1680 OC 24/7 (was fine at 680 on the core).
