i'm thinking of upgrading from 5670 to either of these cards.

6750 which is 105usd
or 6770 which is 120 usd

so which one would be better choice for gaming purpose
(i know 6770 is faster but i comsume more power and more cost)

my monitor will be 1080p and i just want high setting (not the max)

thanks




and any software to test gpu oc (like prime 95 on cpu oc) to test.
my CCC pass the oc result but i got crash with my 5670.
so is 5670 not capable of OCing or just need to test with any tool?

More about : 6750 6770

Prime 95 really push your system. Which program did you use to overclock your gpu? I suggest MSI Afterburner. It was able to detect my GT 240 while others couldn't. As for the two graphic cards, I would get the 6770 but wait for a good MIR offer. http://www.hwcompare.com/5682/radeon-hd-6750-vs-radeon-... The 6770 will use more power [obvious] but you will get better performance and the 6770 should last you. My friend plays high setting with his 5770 [6770 is rebadged 5770] on games like WoW, Starcraft II, and League of Legends with amazing fps. I know they're not intensive games but the 6770 will be able to handle more.

If it helps, he uses a Hannspree 28" 1080p or something like that.

thanks bro
i know 6770 is better but i'm also worried for my psu :) 
my psu just have 400 W 80+
but i worried it can't handle 6770.

i use CCC to oc my 5670. i set the gpu and memory clock, test with CCC and passed. but in the game, the graphic crashed. so anything to stress the gpu like prime95 on cpu.

and one more question, which one is better between 240 1 gb ddr3 and 5670 512mb ddr5 (both stock speed) for gaming (dx11 not considered)

thanks again.

I would go for nVIDIA due to stronger driver support. I would say between the gt 240 and 4670 is pretty even though. You have a 5670 [I'm not up to date with graphic cards haha]. 450W minimum recommended for 6770. I wouldn't get the 6770 unless you're using a reputable power supply that can handle overload [Antec, Corsair, Seasonic, XFX/ Anything made by Seasonic]

^ nvidia doesn't have "stronger driver support", they have issues like everyone else on occasion. My AMD card works flawlessly as did my previous Nvidia card. It has literally been at least 8 years since i can recall actually having a driver issue with either brand.

so 5670 is stronger than 240, right?

what the power draw difference between 6750 and 6770?

i guess 25 W without OC?

and is there any tool to test GPU OC?

I Am using the 6750 right now, couldnt buy the 6770 as it was out of stock. and at 1280 x 1024 , it maxes out all games on high settings. even crysis 1 nd 2 runs well at ultra, 4AA without Dx11. haven't tried the Dx11 patch yet because of slow internet connectivity to download it.

Basically the 6770 is more powerful than a 6750, but at resolutions lower than 1600x900 you won't see much of a difference. Also, my 6750 is overclockable upto 840 Mhz nd 1200 Memory(tested And verified by Furmark).
I Use It At Stock (720 Mhz) i haven't had to overclock it for any game till now.
Also the max power usage of a normal 6750 is upto 90W, and 6770 is 110W, a difference of just 20W. but while overclocking, the difference might increase.

my final verdict is, if you have the money for a 6770, then get it. A 400W 80+ PSU With Atleast 25A on Its 12V Rail Will Handle the card well.
Just post your ratings of the psu, its make and model here and we will tell you.
also post which CPU you are using, amount of ram,Hdd's etc.

Furmark is a software used to test GPU stability nd temperature. However it stresses the GPU a lot more than any game would, so adjusting your OC according to furmark will always ensure you are safe!

also there will be a table with all the ratings in a table. like, there wll be values against 3.3V,12V,+5.5V Etc.
