Hey guys, I have a new computer that came with ATI Radeon HD 4650 PCIE 1024MB Video Card.
However I have a old BFG NVIDIA GeForce 7600 GT OC 256MB PCIe.

I know these are just entry level cards but any suggestions as to what is better? The games I play are COD and SC2 (when its back out :()

The HD4650 without a doubt.

The 7600 GT is completely useless ...

The HD 4650 is not only a lot faster, but also supports HD video acceleration, HDMI output, consumes less power, makes less noise, puts out less heat, and has better driver support.

256mb vs 1024mb dedicated memory.

obviously the 1024mb 4650 is better.

yeah the main thing i saw was the way bigger amount of dedicated memory, but what threw me off was the memorcy clock and memory bandwidth

BFG:
Memory Clock 1450MHz (vs. 1400MHz standard)
Memory Bandwidth 23.2GB/sec.

ATI:
Memory Clock : 800 MHz
Memory Bandwidth : 8 GB/sec

haha anyway, thanks everyone

i picked up a 7900GT for my parents @ FS for 20bucks... it wasnt bad and performed.

I have an asus EAH4650 at work and it performs reasonably well and it has an huge heat sink.. it does not use external power which the 7900GT had.

haha anyway, thanks everyone The ATI Memory Bandwidth makes no sense ...

The 4650 should use a 128-bit bus which, at 800 MHz, would give a Memory bandwidth of:

800*(128/8) = 12800 MB/s (12.8 GB/s)

Even if, for some bizarre reason, the manufacturer opted to use a 64-bit memory bus, the memory bandwidth would be:

800*(64/8) = 6400 MB/s (6.4 GB/s)

8 GB/s w/ 800 MHz memory would be impossible ...
