Money isn't an issue between these cards really, I am putting this all in:
Case Antec Three Hundred Illusion
CPU Intel Core i5-3570K $220.00
Cooling Fan COOLER MASTER Hyper 212
MotherBoard GIGABYTE GA-Z77x-UD3H
Memory G.Skill Sniper 1866
PSU CORSAIR CX Series CX650 650W Power Supply
Hard Drive Seagate Barracuda ST1000DM003
Operating System Windows 7 Home OEM
Anyone out there, should I upgrade to a 7970? I just don't see the value, I do plan to overclock. Also, should I scrap my Radeon love and just do a 670? Many thanks guys, I am sold on the 7950, but if you honestly think a 7970's bigger bill is worth it (hope not) or an equivalent on price and performance Nvidia card is out there, let me know. Thanks again!
I have the Gigabyte 7950 and I have manually OC'd it through the bios w/o probs but due to keeping it simple I primarily run it through the Catalyst Control and manually move it up there (extemely easy) and I run at 1150 mhz in my games np, also used AIDA64 for stress test on it and it never gets higher than 50c .. Awesome card imo, i struggled with the same decision and thought gigabyte was best value.
I'm not sure the MSI card would be the better overclocker over the Vapor-x mainly because there are stronger versions of the twin frozr card then the revision you linked which the 7970 uses the twin frozr iv revision which the 600 series cards also take advantage as well from the Nvidia camp. And the Vapor-x has higher quality caps, mosfets, and chokes.
Black Diamond Choke & Full Solid Cap Design
Choke is an important component of the graphics card. By working with the component engineer, Sapphire’s patent pending choke is 10% cooler and offers 25% more power efficiency than a normal choke. The graphics card will be more reliable and save energy.
Improved reliability and better overclocking are possible by using only high-polymer, aluminum capacitors which posses far superior characteristics than regular aluminum capacitor for a longer product life. When operational temperatures drop by 20°C, the product life span is extended by a factor of ten, when the operational temperature increases by 20°C, the product life span only decreases by 10%.
