Phenom IIs like that are about equal to an equivalent-clocked Core 2. (Edit: Or
maybe a little slower.) The main reason to get a Phenom X2 is to try to unlock it to an X3 or X4. If the mobo you're getting with this computer doesn't support that and/or overclocking, I'd generally suggest looking elsewhere. A G530 will at least equal that processor at stock;
a G620 will soundly beat it.
