I recently built a gaming PC, the specs are:

-3570k
-G.Skill 8gb 1600mhz ram
-Gigabyte UD3H
-Sapphire 7950
-TX 750 V2
-Corsair 60gb SSD + Seagate 1TB HDD
-HAF 922

It's a real improvement from my e7500 and radeon 5770. I have OC'd the CPU to 4.3 without touching the voltage and the same goes for the GPU which runs at 1100 & 1500 with a 20% power increase - I am very satisfied with these overclocks and the temperatures seem to run fine (79-85c max with the CPU in a FFT test using prime 95 & furmark burn in test has the GPU run @ 78c max); I know the IB CPUs run a bit warmer and I also know that the furmark burn in test is very stressful on the GPU - in game @ 100% the temperature stays 69-71c. Also, my room temp is a bit on the warmer side. What do you guys think about these temps? As for the GPU performance I was able to use Unigine 3.0 and at stock settings I got an avg FPS of 39 and with a strong OC I was able to get 47 - what do you guys think about that? Is this a reliable GPU test?

My only concern is that I'd like to keep this PC without upgrading any components for at least 2 years. I am thinking about adding a second 7950, but only when the card sees a drop in price. I am worried about getting this card from a retail shop before the 8xxx cards appear and these disappear. I don't like purchasing expensive electronic products from individuals, whether new or used; when is the latest (& cheapest) I can get this card before it's discontinued? How early did the 6xxx cards disappear when the current gen was being launched?

Thanks.
 
i take maybe 2 years from the initial launch before the cards starts disappearing. not sure when AMD wants to EOL the cards though. AMD tends to update their line up once a year (which is around Q4) but this time amd intends to prolong the 7k series life by releasing the next series (the HD8k series) around Q2 2013.
