You make it sound like the Q8300 is a bad chip or that you had that PC long. Max you could have that system would be 2 to 2.5 years. I had a PC for 5-7ys before I upgraded.
I'm calling it now so bet me $100 if you want - you will upgrade again to GK110.
That PC actually had a Core 2 Duo E6300 at 3GHz before the Q8300 and the 9800GT was before the GTX260. Im just saying that I can survive on older less expensive hardware, because at the time, i7 920's were very popular and everyone loved the GTX295 and GTX285 ...
Cant deny that I wont upgrade to GK110 but cant confirm that I will upgrade to GK110 Depends on its price, what the 2nd hand market for 680s will be and if the wait for a lower nm die shrink is going to be too long.
Maybe I'll treat myself to a GK110 for Christmas
