Intel Core 2 Quad CPU This is a 64 bit CPU will this have problems running 32 bit vista software as well as other 32 bit software? Should I get this or stick with the Core 2 duo CPUs?
All modern CPUs have 64-bit capability. They are shipped with 32-bit enabled unless shipped with 64-bit OS. 64-bit OSs run "32-bit emulation" on 32-bit apps. Totally seamless. You won't even notice.
I have a C2Q setup with a 32 bit OS system. No problems. Very smooth. I've been reluctant to upgrade to 64 bit because of compatibility issues with older stuff.
Speaking of quads, I have a T3400 with Q9300. I also have some other computers with E8300 C2D. For trading, I see virtually no difference... maybe a slight difference in loading-up apps to get started. After that, nearly everything runs from RAM and the CPU sits mostly idle during the trading day. I recently did a fresh install on the quad and also had to do an update from a several-month old image on my Vostro with E8300. I noticed the Vostro to be quite "pokey" at doing the updates. The computer's speed has to do with more than just the CPU. A good mobo adds to performance.
