Hello, I recently built my own computer with a sapphire 7790 as its graphics card. A PNY Geforce 8800 GTS was given to me, and I want to know if I could hook them both up in my computer. I have a XFX 550 watt core edition psu. Any help would be great.

You cannot sli/crossfire 2 cards from completely different manufacturers.
The 8800gts could possibly be used as a dedicated Physx card but it would be pretty pointless and your power supply wouldn't handle it anyway.

Okay, why would it be pointless to have a dedicated PhysX card? That was my plan if it did work.

Are you saying my 7850 is pointless? lol
I just meant as he only has a 550watt power supply so it wouldn't be worth it.
I get my new PSU and 280x next weekend:)

As i said
"I just meant as he only has a 550watt power supply so it wouldn't be worth it."
If he plays games with Physx and wants to buy a new PSU then he can it's his choice.
When i had a Nvidia card i never found the Physx worth it so it's pointless for me. It was just MY opinion.I already said it was his choice and he was asking opinions
 




It just came across as the opinion of an AMD fan which like the comment in bold is not worth much, I've had an XFX card and an Asus card in SLi and they are two different manufactures so how comes that worked?

Okay maybe i could of been clearer as i meant 2 different manufactures as in an AMD and Nvidia card can't sli/crossfire together. I am well aware that an Asus and XFX can sli together.
As for being an AMD fan i think you assumed that from my build. The FX8320 was cheaper by £60 to the intel CPU i considered buying.
As for my AMD graphics card it was the best performance/price ratio at the time i got it on sale.
Before i had my 7850 i had an AMD 6850. In the years before that all my graphics cards have been Nvidia all the way back to my Geforce 2mx with 64mb of memory:)
I have an AMD build but do not consider myself a fan. My next build might be an Intel/Nvidia combination
