Well just the fact that any card he might be settling on now is likely going to accrue a price drop in the next couple months is reason enough to be slightly patient. If he is looking to future proof a bit more, a few months will get him a better option and gives him time to save up more for the price difference.
But then in january I can wait for the april releases because then the new cards will be cheap, and then I can better wait for the october releases etc.
The new ones come to quick to actually bother with waiting. But that's just a matter of opinion anyways.
I did see at a dutch vendor of several acronyms behind the names. Stuff like:
- HD
- (HD) SC
- SOC
- OC (overclock I guess)
- DirectCUII
Also one card does have 2.5Gb instead of the 1.28Gb, but does that card really use it or is it just useless extra memory?
