botneck amd athlon 450 hd 7750 crossfire

post #1 of 6
Thread Starter 
]hey i plan to run one hd7750 and a hd7770 in crossfire
my question is if my processor will keep up
I have an athlon 450 oc to 3.7 ghz

and what happens when you run out of graphics RAM will it lag a lot or what?
Thanks for your anwsers smile.gif

You Should Be OK, it wont slow down. If anything it will lag from the beginning.
You CANNOT Crossfire 2 different cards. Flashing the 7750 is RISKY
Your best bet to Crossfire would be to find the same exact used card on Craigslist or eBay or even on Overclock.net

i had an athlon II x4 640 and a GTS450. i eventually upgraded to a GTX460 and had no problems.

Goodluck!

in your case it would be like runnng,2 7750s.the faster card will default to slower cards speed....u can crossfire those cards,but i think what that guy meant was ud want to,use da same carda for example 2 7770s would be better then 2 7750s! I recently read there was a black edition ataha:rolleyes:lon,i had no idea!

unlock your athlon to a quadcore and you dont have to worry about bottlenecks.
Although at 3.7 Ghz, im sure even at 3 cores its more than fast enough.

I estimate 7750 crossfire should perform like an HD7850, maybe a bit faster
