GTX460 performing terribly

My system is old, I'm running a Q6600 at stock clocks with 3 gigs of ram (I lost my 4th stick...lol). However, with my 8800GTS 512 and my CPU at 3.6ghz and 4 gigs I hit 15,782 3DMark06 when everything was fresh.

Today I dropped a GTX460 768 in today and got 5542 on the same benchmark with the newest drivers. Battlefield 3 was unplayable on medium and pretty bad on low and Skyrim was a 2 frame per second mess on the same max settings my 6950 2gb ran it at with 0 choppiness. The 6950 is a faster card, but not 20x faster. What could be going on? This card is definitely performing worse than my 8800.

Did you install drivers for GTX 460?

I just swapped my 6 pins on the card. One of my 6-pins is actually labeled PCI-E but the second one is just coming from one of the modular hookups on the PSU, I'm assuming it isnt full voltage. My 3dMark score jumped to 13000 which still seems kinda low with 4844 SM2.0 and 6406 SM3.0. It is a synthetic benchmark taking my CPU into consideration but that still seems too low. I'll try BF3 now.

EDIT: not full current probably? I'm not much of an electrical engineer

Sorry for wasting you guys time, feel free to delete this. Swapping the power connectors made it so BF3 runs on Ultra. If BF3 runs on Ultra the card is performing properly. I guess that means one of the power inputs on the card is the dominant one and my permanently fixed PCI-E 6-pin connector puts out more power than the modular outputs. Thank you!

Glad you solved it :) .

I wish the card said "put your good plug here" :o

but seriously, how would I have known that one was more dominate than the other, they look the same. I'm pretty sure underpowering a card is pretty much the worst thing you can do to them too when it comes to burning them up.

That's correct, I don't really know why it happened. Maybe the power supply is faulty? I mean, the modular 6 pin should be as good as non modular one. Are you sure you plugged the other end of the 6 pin to the right place on the power supply unit?

Nope, I'm not sure. All of the modular outputs on the PSU look the same and lets be realistic, I'm not looking at any manuals when it comes to computer parts haha

I'm going to try bumping this one more time. It has been about 6 months of frustration and I don't have the money for a new GPU at the moment.

Is there anything I can do that could possibly fix this card? Anything? I've had at least 4 GPU's in this computer and I've never had this issue. I can't figure it out for the life of me.
