GPU OC noob here

post #1 of 5
Thread Starter 
I was looking at this deal on Newegg

http://www.newegg.com/Product/Produc...82E16814150252

For about $350 I could SLI these, but I was wondering how high I could OC these before a noticeable temp change. I've never messed with clocks on video cards, so I come to you. Will I even NEED to OC these?

uh these card are fine overclockers.. but the temperature would be high.... i prefer an aftermarket cooler or watercooling if you want to overclock them high

Otherwise i would go for the 8800 GTS 512, mine is not stable with ATI tools, but its stable in every game i played, planning to get my 2nd piece to reach 40-50 FPS in crysis, currently running crysis on HIGH:46 LOW: 29 @ 1680 x 1050

Will I see THAT much of a performance difference if I overclock it? What are the other things I need to OC besides the Core Clock?

To be totally honest with you, in all my years of system building, overclocking, and gaming, using dozens of different rigs and perhaps a dozen video cards, I've only come across two cards that overclocked well enough that overclocking made a tangible difference in the settings I could comfortably play a game at ... and even in those cases, what we are talking about has been something like being able to use 2xAA instead of none, or playing at 1600x1200 instead of 1280x1024, on a select handful of games.

Those two cards were my old 7900GS, which OC'd by a whopping 30% core, 25% memory, and my present sig card, which OC's by about 25% core, 28% memory.

When you really get right down to it, in most cases, overclocking is about your e-peen and benches more than it really having a practical application. Again, as I stated above, depending on the game, card, and settings you're playing at, it's *possible* that you'll run into cases where overclocking can improve on your 'playable settings', but it's very rare that it will be by more than one notch on one (major, like res/aa) setting, at least in my experience.

And given that your average 8800GT doesn't OC by much more than 15% ... my inclination would be to say that no, you don't probably don't NEED to overclock your card(s).

But it's still fun to do

Like he said, go with the GTS, if you want to OC a GT, you need aftermarket cooling, and after that, you would have spent the same amount it would have taken to get a GTS in the first place.
