I recently bought A10 laptop like good 5-6 months ago. Thinking of getting 17inch Sager laptop. 7970m crossfire or 680m sli? Does Vram make any difference? How about processors? 3630qm vs 3740qm?

Beyond 1 GB of VRAM, it's useless unless if you have the desktop 7950's or 670's processing power.

I don't see how that's at all true...

The 5870 had a 2GB model and it used it all in most DX11 titles. tongue.gif Heck my 6970M uses upwards of 1.5GB in most of those same games. AvP, Crysis 2, Skyrim uses the full 2GB, etc...

2GB is plenty for games, but it needs the appropriate horsepower behind it. The 675MX is powerful enough to push about have of it's framebuffer, which is good enough for any DX11 title at 1080p. tongue.gif

3gb of vram is ideal for the next 4-5 years, some games with texture mods reach 2.3gb maxed out atm

The question is, does the mobile GPU have the graphic processing and memory bandwidth to take advantage of VRAM usage beyond 2 GB?

The higher end models do. The 680M and the 7970M. You've gotta overclock the former of those two to make the most out of it, but the graphical horsepower is there.

Anything lower than that will probably get close to 2GB of Vram. tongue.gif

According to this test, only Sniper Elite V2 and Metro 2033 Last Refuge used more than 2 GB of VRAM on a 4 GB GTX 680, after running them in triple-monitor mode: http://www.xbitlabs.com/articles/graphics/display/evga-geforce-gtx-670-4gb_11.html#sect0

I'm sure most games TODAY don't use that level of VRAM but I wouldn't be surprised if that starts to change soon.

My modded Skyrim takes up to 2.3GB on a single 1440p monitor. That's for my "lightly modded" version, I haven't installed all the mods I want yet on there but I wouldn't be surprised if I started to pass 3GB.
