ahh, saw your other thread, but even at triple-monitor resolutions, 2GB doesn't look that bottle necked. besides, the bottle neck is created by the 256-bit memory bus bandwidth, not really by the 2GB of actual capacity. buying a 4GB 670 aren't going to fix that...
anyway, I say go for the 7950s. in case you're wondering, the memory bus is 386-bit
Grab a Sapphire 7950 OC. Better than the Gigabyte in benchmarks on various websites. Check it out before you lay down cash for the Gigabyte. Sapphire just released a new OC 7950 version with an out-of-the-box clock speed of 950Mhz and a higher quality PCB.
True, except I am looking for the 4GB model and the evga sc editions seem to be giving people problems having being recalled as well. The only other 4GB 670 is zotac which I don't know if they are any good.
Another thing is the 7950 is 386 bit bus, and the bench marks come pretty close to the 670.
your best bet would be to get the XFX one for $305, save up and get another one for a similar price. you'll be very close to the performance of the 690 that way, without the 2GB/256-bit bus memory issue of the 690. thus you'll have an ideal system for multi-monitor gaming for nearly $400 cheaper than a 690
That would be good if I was going to CF, but the 950 mhz clock on the sapphire looks like it will give good performance for the next 3 years. However the 670 outperforms the 7970 in most cases, so I'm not sure whether $400 for a 670, or $400 for 7950 w/ 386 bus and extra gig of vram which will probably prove useful in the next 3 years.
I'm looking to keep the card for 3 years playing at 1080p resolution. I will be gaming on one screen, while running basic apps on my other two screens.
The 384 bit bus plus 1 extra gig vram has me leaning towards the 7950, however once the 670 gets a driver update I'm sure it will be running flawlessly as it easily outperforms the 7970.
last I remember you're running multi-monitor? I can guarantee you that a single 670 or 7950 will not be running games flawlessly on 3 screens in 3 years, your easiest upgrade route will be to get a second one and CF or SLI, in which case the 7950 has a huge advantage over the 670 due to the 384 bit memory bus (it can actually handle it's 3GB of memory efficiently).
on the other hand, if that's not your upgrade route, get the windforce 670 and be happy with it. at the same cost, the 670 wins hands down
