Can I use two different graphics cards

[Malakesher]

Hello
Currently I have a HD 7750 1GB in my pc and I am about to upgrade parts of my pc to make it better for gaming. One thing I want is a better graphics card but the one I currently have still works perfectly fine and is pretty new. I just wanted to know if I need to replace this or if there is anyway of using it with a more powerful card to add to its abilities. Also what problems or limitations it may cause.
Sorry if it's a stupid question and thanks for your time.
Liam

Yes, but it has to be a compatible one with the motherboard and PSU, the PSU needs to be enough Wattage to handle another graphic card which is around 150W itself.

Hope it helped.

To check if its compatible: www.pcpartpicker.com or just go to the manufacturers website.

You can buy another 7750 and do a crossfire.

I had considered a second 7750 but I have about £150 - £200 put aside for the graphics Card and want to get the best I can overall. Also when I have worked out what I will be getting I will be replacing my psu.

Another 7750 will work good for you.

i honestly wouldn't bother, unless you need to run more screens than any single card can support. running dual 7750s in crossfire is like... i dunno... welding together two SmartCars and calling it an S-Class. yeah, no go. two shitty parts don't add up to one good part, just two shitty parts instead of one shitty part.

shitty being relative. i'm sure a 7750 is fine in its own price range and for what it is intended to do, but you're FAR better off selling it or using it elsewhere and just getting ONE GREAT card. if a game you want to play doesn't support dual cards, it'll just use one card - now, do you want that one card to be a 7750 or a 7870?

If I don't continue to use the 7750 it will sit in a draw somewhere as a backup incase the new one ever fails then at least I will have something so not using it won't be any benefit to me as in selling it or using it in a second pc so I mostly wanted to find out if there was still a use for it next to a better one?

you can run it for additional monitors and use your new big card for the main gaming screen, but some folks say that multiple drivers can have a negative effect on this. i don't know how true this actually is since my game machine is an ITX build so i can only run one card anyways, and i run 3 cards in my work machine which isn't used for games so.....

it's too new of a card to just stuff into a drawer and ignore it, but doubling up on it with another 7750 is probably not the most effective use of your money.

what's your processor? does it have onboard graphics? if it does, then keeping the 7750 as a spare while your new card gets repaired/replaced doesn't make much sense. maybe better to sell the card and use part of the revenue to buy an in-store instant-replacement warranty if they offer it. or stuff the money in the bank or throw it at your credit card - financially you'll be further ahead.
