VERY good to know! Yeah, my laptop GPU is actually pretty good for running HLSL in MAME as the monitor resolution is only 1680x1050 which isn't super massive. The new monitor I bought for the cab I'm building is 1920x1080 I believe, so that's not a massively detailed resolution either. For the stuttering issue I started this thread about so many moons ago, it is indeed caused by the graphics card in my laptop throttling down when the GPU temp increases due to the workload. In the cab I'm building, there will be PLENTY of room to allow the GPU to remain cool and not overheat, thus enabling the throttling.

I was just more confused about what was better, more RAM or a higher clock speed. Since my laptop's clock speed is good enough to initially run HLSL for a good five-ten minutes before overheating, I won't need to go and get a super fast, expensive modern card. I think I'll shoot for one that has a good deal of RAM and a good cooler on it. I'm not concerned with running the most modern 3D games in it since the cab is being built for playing Street Fighter games.
