I needed to replace my motherboard and processor that isn't playing nice with my GeForce 460GTX. The ASUS board was replaced with a Gigabyte board that wouldn't accept the original 8 year old processor. which is another AMD Quad. The memory was upgraded to DDR3 from DDR2, but being the tech only had 6 gigs that is all he put in. There were 8 gigs in the former. Needless to say none of this is playing nice with my Vegas programs or video intensive software. The tech tells me the video card is bad, but I'm thinking it is a memory issue. I had a good long run with my previous setup. Never a problem as those developed now. Any suggestions short of going out and getting a dedicated workstation or expensive build would be appreciated. I cannot do a thing with Vegas as it is now. Playback of everything is fine. Making anything is mute.
