A question of compatibility
Hello
I'm currently running a Z77A-GD65 (MS-7751) motherboard and 2 GT8800s in a sli configuration. The graphics are becoming a bit chuggish and I believe its time for an upgrade. My questions is whether any new graphics cards will be compatible with it (i.e. GTX 670/780 or their radeon equivalents, DX11 is imperative) as i'd like to keep the rest of the internals. PSU and case won't be a problem as they resemble a small power plant and mini fridge respectively

Haha ok lets just put that in context.

Unless PSUs are of utter junk, they rarely fail unless put under more stress than they can handle. Since your PSU was fine with the SLI setup bordering on 700W draw, you will barely be pulling 600W from the PSU AFTER this upgrade.

I am sure you will not have a catastrophic failure BUT it is possible.

Most PSU do have protection to avoid these things, but without having a thorough analysis of your unit, we can not be sure that all the protection needed is present.

But I stress, if your PSU wanted to fail, it would have done so already when you SLId 2 8800GT's.

CGurrell stop scaring the users! :p 



Ah, I see, I could already envision the inferno that would be my PC in the case of a PSU failure, doesn't seem quite that dramatic now.
Thanks a bunch

CGurrell, thanks for the warning, but you now owe me a pair of pants


LOL! Sorry about that :p  Just make sure not to overload the PSU (as in, replace it before crossfiring the r9 290) and you should be fine :)  I may have exaggerated a bit as I've seen people with generic 300W PSUs wanting to buy GTX 780s and I just blow a gasket :p 


Lol, thanks for the heads up

If the PSU dies, be prepared for something else to die at the same time...


That sounds both ominous and expensive, please elaborate on this message of doom you bring. You saying that if my PSU kicks it it doesn't go alone? I thought these things had built in surge protectors or something. Are there any signs that your PSU is planning on committing a murder suicide?

No problem! Have fun! One hell of an upgrade.

You will need a better PSU as its a pretty power hungry card, but it does. :) 



Excellent. Thanks a lot for all the help folks. You have probably saved me from wasting a bunch of money on unnecessary parts. I'll be placing my order in the morning

REmains the same.

You do not need any more than a R9 280x / GTX 770 for decent FPS and high to extreme settings at that resolution, but an R9 290 would still be my suggestion for some future monitor upgrade or games that may require more GPU muscle.

So short answer :

An excellent suggestion

Now a question about the card, assuming I want to do some more upgrades in the future, does this card support crossfire?
