So I am looking to buy a new computer for work, but not sure what to go after. I don't store a lot of files, mostly just spread sheets and word documents, some pictures, so memory may not be a big factor in this purchase. What I need to know from you computer savvy Titan fans is; is the processor type a big deal? And if so, which processor should do I want? I'm currently using Intel Pentium 4 and processor Speed 2.73 GHz . Is something like an AMD Athlon better?
