I'm considering upgrade vs. new build, but would only want to upgrade the GPU. I just don't know it the rest of then system could handle it.
Core 2 Duo E6600 (not overclocked)
Asus 975x Mobo
8800 GTS 512 GPU
This is for gaming.
If I upgraded to 5870 GPU, would it be bottlenecked by the rest of the system? I'd definitely want a big FPS improvement. I would drop in the new card now and then also use it in a new build in a year or so, possibly with a 2nd one in crossfire. Otherwise, its time for new build now.
The answers are yes and yes. Yes, you will see a bigtime improvement in FPS. And, again, yes your CPU will bottleneck the 5870.
I once had the same CPU OC'd to 3.4Ghz and it bottlenecked my 260 Black Edition. However, I was getting about 30-40 fps playing Crysis on Win XP w/ DX9.
Go for it, you'll get a big-time improvement over your 8800gts, but will not unleash the full power of the card. Before I got the Black Edition 260 GTX I was running an evga 8800gta and got a dramatic improvement.
Ok that's good to know. I suppose I could live with not getting all that I'm paying for out of the card if its still a lot better than current performance. Maybe I'll reconsider and get a 5850 instead, with an eye towards SLI with that later.
