macbook pro graphics card question

NVIDIA GeForce 8600M GT graphics processor 128MB of GDDR3 SDRAM
---does this mean that the maximum memory the graphics card has is only 128mb?

 

It means it has 128 Mb of dedicated VRAM.

 

can i overclock it?

 

Yes with the new drivers(don't know if you can with old ones) that just came out you can.

 

You can, but only having 128 mb of video memory is going to be far more limiting than the actual clock speeds of the graphics components.

 

but is 128mb enough for gaming medium power gaming
is it worth to add like 500 more for 256mb in mbp

 

Depends on what you're playing. Half-Life 2 should run acceptably at 1280x800 with medium/high details. For Crysis, you'd probably be stuck at 800x600 and low details. Older games shouldn't have a problem.

 

so would 128mb be enough for half life 2 and other older games?

 

Yep, definitely.

Having 128MB of VRAM isn't as much as of a limiting factor as some people say it is. It mostly depends on what games you're playing and at what settings you want to be able to use. More VRAM will help out noticeably on newer games with large texture loads and at higher resolutions (or with AA on), but for other not-so recent games (not from within the last 6 months) it becomes much less of a factor.

 

Actually, HL2 and probably most (if not all games) using the source engine, run perfectly fine at native res, with almost every setting maxed out.

As for Crysis, if the demo is anything, it is very playable and you can have the settings at medium and play fine.
(I feel bad, but it completly slips my mind what resolution I played it at. It might have been native res, but I kind of doubt that, if anything it was 1380~ but it wasnt 1280x800)

A lot of people bash the 128mb version of the card, but it isn't as bad as some people make it out to be.
