I bought an 8800 GTX off ebay. It was supposed to be new but it didn't come in its box, so I'm beginning to doubt that.

I'm building a new computer and my old computer cant hold it but I have a friend with an 8800 GTS and we tested it out on his computer. For some reason it runs waay slower on all his games. It seems really hot too so maybe it's underclocking itself because the fan isn't working right or something. This was on Windows but is there any reason an 8800 GTX would be really slow? You'd think it'd either work normally or would just be broken, not somewhere in between. It could be drivers or something but I think the card might be jacked.

If there is one thing I never really liked buying off eBay were computer parts. They could have been overclocked without proper cooling, stored in wrong places, not properly handled, etc.

But anyway, I'd recommend you a few things:

- Make sure the card is getting enough cooling. Even fanless cards almost require at very least a case fan near it. I have a 8600 fanless card and it was highly recommended to have a case fan:

And my card is pretty bad, especially when compared to both your cards . So cooling is important here.

- Make sure the card is getting enough power. Nvidia cards are getting more and more needy. Make sure your Power Supply is up to the task;
- Test with another driver, even if older. Sometimes new drivers can have some bugs like that.

Good luck there mate!

On windows there shouldn't be a problem finding out what is going on.
Try 3dmark,sandra,ntune (piece of crap but works for some) or atitool.

Was it advertised as OEM (OEM is w/o box).If so check with the manufacturer if they even sell OEM.
Got stickers on there?

What CPU do you have? How much memory? How are you determining it is slower, what games?

I'd be scared of buying things off ebay too. Parts could not be handled correctly, people are saying that they are a certain product and be fakes (btw, google for a program called GPUz, and show us a screenshot of what it says), could've been a dud product, could've OC'd it and caused damage.

Actually yeah it says it was oem and came with a front plastic peel-off thing. And the seller does have 100% positive feedback, it looked legit when I bought it.

It's possible that it wasn't getting enough power. I guess I'll find out when I get my computer put together.

Even if it is new I heard sometimes stock processors for whatever reason can be bad or good, especially for overclocking. Can video cards come out of the factory bellow average sometimes? (not talking about the atis a few years back that we're essentially the same hardware just locked and you could unlock it somehow to be a better card)


edit -- btw we were using ntune. The games were crysis and dirt (racing).

How much slower was it? Did you wipe off all the drivers from the old card and installed the latest drivers from nvidia's page? Never use the drivers that come in the cd.

Try to figure out what goes on there running a benchmark and monitor the card at the same time.
If something is odd try to return the card - if it is a new OEM it shouldn't be a problem if the seller is legit.
If the seller isn't legit you are screwed anyway.

BTW - ntune sucks.Wouldn't trust that thing the slightest bit.If you want a real benchmark get 3dmark and see how it stacks up.

Edit - forgot: Bad cards do happen.That doesn't necessarily mean the guy tried to screw you over if the card turns out damaged.
