Anyway, in Photoshop there will be no gains from extra graphics card memory. Technically, your screen in windows is one big texture that the graphics card is constantly rendering... but it isn't significant enough to drastically effect performance. It would be an issue if you were running at 8000x6000 resolution (don't see that happening anytime soon!) with only 4 MB of ram.
Actually, right now I'm working in 4000x3000 with 8MB of RAM.
