|I'm not sure I understand your question because of the lack of information. You should make sure to get a list of the systems specs and post them, so that it may be much easier to provide you the information you need. |
From the information you've given I can only guess... I'm guessing that it's a Dell with an AMD Phenom X3 8650 (which has 3 cores NOT 8) with "a lot of ram" which seems suspicious from the person selling you a 8650 Phenom with 8 cores when it only has 3 with 2.30 GHz frequenzy. It maybe that the person you are buying it from is overating it.
To answer your question especifically: No; this machine would not be good for gaming.
In order to have a mid range gaming rig, which would be not so much good but okay in my opinion, it would need to have a 4 core CPU, with at least 4 GB RAM and most importantly a mid range video card (depending on monitor resolution), like a nvidia GTS 450 or ati equivalent.
Hope this helped... "/
