Just a general Q about gfx cards really. My current 6600GT is oc'd to 550MHZ and 1150 for the memory. I'm selling up for a PCI-E sapphire X1950 pro, which is 580MHZ/1400. Is it the speeds of the cpu/memory alone that determine the performance of the graphics card, or say if you could theoretically clock my current card to the x1950 pro speeds, would it still fall short?

Gfx cards: is the CPU + Mem speed all?

Are you saying if you clocked the 6800 to x1950 it would be the same speed?
Erm, no.
Different cards, different designs. It doesn't work like that. The X9150 at stock is a good 50% better than the 6800, maybe more as I haven't really looked at benchmarks, but its around X1900XT 256mb speeds

beast said:Good to know. It's a BFG 6600GT OC I have, not a 6800. What I'm saying is, is the 1950 pro gonna blow me away or will it be just a slight difference? I want to be blownaway
Blow you away tbh.

You should see at least 3x the raw performance - probably more.
To answer your original question - no you can't compare clock speeds.
These days, even CPUs are usless to compare clock-for-clock between brands, but with video cards it's much more so. You have different numbers of pixel shaders (which you can think of as 'separate' internal processors which feed information on within the GPU) on different cards, and different memory bus sizes.
Recently a good rough rule of thumb has been that each new generation is roughly twice the speed of the previous generation, and the high-end cards are around twice the speed of the mid range cards. You're going from mid-range generation 6 to (fairly) high-end generation 7. You will see the difference.
Yes! Great stuff! I just didn't want to get my hopes up and be dissappointed but it sounds like I'll have to pick up my jaw from the floor.

No. Core speed and memory speed are only two of the factors which determine how fast a card are. Other contributing factors include, but are not limited to:
-Number of pixel pipelines
-Number of vertex pipelines/shaders
-Memory interface (e.g. 256bit, 64bit etc)
-Memory timings (not overly important)
-Amount of memory (generally only matters at extremely high settings)
-Drivers (example: Prior to the 8500 series and Catalyst drivers, ATI's hardware was let down by poor drivers)
