So I play World of Warcraft on my MBP and my friend has an old iMac with the ATI Radeon 2600 in it. I am using the Nvidia 9600M GT. My friend has 4GB of memory and 256Mb of VRAM (same VRAM as me). However I only have 2GB of memory. Would this cause a preformance loss to me on my part? Because they have none of the problems with "lagg" which I do. My Frame rates are about 30 (except when I lagg) and my friend get 40, my Latency is always 50-65ms,same as my friend. Basically the question is: is it my lack of 2GB more memory, or is it that the older ATI Radeon 2600 is better than the Nvidia 9600M GT that makes my game preform badly? (I was under the impression that the Nvidia was better after looking at some benchmarks)
