Since I am planning to upgrade my GPU from a 7950GT to a GTX 260 or 4870/90, I am concerned that my CPU might be a bottleneck. I am running a C2D E6600 (2,4 GHz) and because I am not into all those technical details, I am asking you for advice. Hopefully, my CPU won't be an issue - otherwise I would run into budget problems ;-) Thanks!
Thanks for your assessments! I am glad to hear that I probably won't run into any serious issues :-)
While narrowing down the selection of cards I might purchase, another question crossed my mind: how much memory should the new gfx card have? Is it sufficient to stick to 1GB or would it be sensible to invest more and have 2GB of memory?
Never buy 2GB cards...they are just marketing tactics to lure in buyers but actually have no performance gains for the extra money...
The current graphic cards, actually don't fully utilize the 1GB vRAM let alone 2GB...
So it is not worth going with the 2GB ones...Instead you can spend the extra money on cards that have aftermarket cooling and overclocked versions...
Alright, thanks to your input I am probably going to buy a 4870 with a Vapor-X cooling system from Sapphire. It seems there is a slightly overclocked ("TOXIC") version available, which shouldn't be too loud with that non-standard cooling system. But just in case I missed something: are there any GTX 260 216 cards available which are comparable to those Sapphire cards regarding noise level and performance? I haven't found any.
I guess my 500W PSU will be sufficient for the new card.
As of today I own a Sapphire 4870 Toxic 1GB graphics card. Seems to be a decent one. Unfortunately, I already ran into an issue that is new to me: When I run 3DMark06 it might happen that during the switch between the tests the benchmark aborts with the following error message: "IDirect3DDevice9:: Present failed: Device lost (D3DERR_DEVICELOST)". Does this mean there is a serious problem either with the card or my machine?
Apart from that I was able to complete one 3DMark06 run (1280x1024 and Optimal Performance settings in CCC) and my system scored around 10500 3DMarks. My old 7950GT scored 5503 3DMarks IIRC. Is the result of the 4870 in line with what one can expect from such a gfx card or is it too low?
