Need to buy new computer

[is14fun]

Thanks for response, I am looking at two computers at sam's. Below are the basic differences:
Intel T4300 2.1 GHz
Intel Graphics Media Accelerator 4500M (Shared) up to 1695 total avail. graphic memory.
4096 DDR2 Memory
Or
ATI HD4650 (M96) up to 2815 MB avail & 102 dedicated
4096 DDR2 Memory.
Both have 500GB hard drives.

The second one is $200 more. Would both of these work & what basic differences would I experierence with each one? Both have Windows 7 64bit installed. I notice some problems with 64 bit and Microstudio. Should I be concerned about this?

I am using the latest version of Hoster on a Dell. Windows 7 with 1GB of memory and 100GB hard drive. I am having problem with Hoster encountering KMA read errors on some of my files. Microstudio does not encounter these errors so I am thinking the problem must be with my computer resourses and the new version of Hoster (ie lack of memory and processor speed). I need new computer anyway as my current one had glass of white wine poured on it and I expect it to totally destruct in the near future.

Thanks for you help on this subject.
