Bit offtopic, forgive me

This is what I've heard, so I am not sure. My card came with F42 & 59% ASIC.
But what I know for sure is most of their cards are below 60% ASIC, if you got one above 60% with a Gigabyte 7950 and overclock well consider yourself lucky.
Best 7950 results for overclocking I've seen are from Sapphire, MSI & Asus.
It still luck dependent so you might have a Gigabyte but a good clocker, but if you read this thread especially later pages you will see most Gigabyte 7950s are duds.

This is true (raghu78 had to school me to make me see the light bulb.gif )

After all the site comparison reviews I've read about these 2 gpu's the 660Ti does not stand a chance. The 660Ti can be OCed to be a better performing gpu over a stock 7950 (non-boost version) but once you OC the non-boost 7950, the 660Ti falls behind again.

The 7950 Boost is definitely way to go between the 2 thumb.gif

Yes, the OC W/ Boost has the dual-x cooler design, thanks for the reply wink.gif

If you won't be overclocking, then the Sapphire Vapor X is your best bet as it factory overclocked.

However, if you feel like you'll be overclocking in the future, the Vapor X is not a good choice, because it is voltage locked. For overclocking, you might want to look for another manufacturers, like Gigabyte.

The PSU is fine. A lot smaller one would do wattage wise, but i don't know about the quality of CM PSU's so it's up to you.

From the replies I will be getting a 7950 then smile.gif I have read on this forum that the vapor-X cards have been voltage locked, then how about the boost dual-x version? Do you guys know if it's locked too?

From what i have grasped from all this, is that all sapphire cards with boost feature cannot be overvolted, due the fact that when the boost kicks in under high load, it will use its own boost settings and voltage, opposed to the values you typed in to the "idle" state. This is Afterburner / Trixx problem but the cards are not voltage locked, it seems. I do not know this for sure, but its just what i've heard.

not true at all. there are many users running the Sapphire HD 7950 boost or Sapphire HD 7950 Flex OC with boost with voltage control. check in the HD 7900 users thread.

I don't really want to touch the voltages (might void the warranty from the shop I am going to buy it from), but it being 50 SGD cheaper than the Vapor-X (in fact it's the cheapest 7950 I can find) should I get the Sapphire 7950 OC with boost version?

Also since I am not really sure of CM's PSU quality, should I instead get a Seasonic X 660W Gold for 168 SGD or a Thermaltake T.Power ST 650W Gold for 145 SGD?
(I really do not mind forging out a few more bucks for a more reliable PSU (though I Know CM PSUs are still of good quality)
