my question is i currently got a computer with a Pentium 4 processor 3.4 GHz and another computer with AMD 64 X2 dual core 4600 at 2.4 GHz so which would be better for gaming
AMD 64 x2 will be better than the P4 in almost every way, and if the rest of your hardware allows, you should get a decent overclock on that CPu to make single threaded agmes run more than happily, the P4 is now very old and long in the tooth.
if you guys dont mind i got another question if i was to buy this http://www.newegg.com/Product/Product.aspx?Item=N82E16814102794 i would need a better power supply and seeing how the the computer with the P4 has a better one could i take it out and put it into the other
The 4600X2. It's not even a contest Even in older single threaded applications that P4 might, maybe, possibly, come up just behind the 4600X2, but in general the 4600 will just blow it away. You can see a comparision on the older CPU charts
^ yes, but it was a socket AM2 Semperion with dual channel DDR2-800, compared to the DDR2-533 the P4 was tested with. That Semperion is basically an Athlon 64 with some of its cache disabled so with the faster RAM it makes sense that it would score higher. Of course those results are still well below the 4600 X2.
