Would the processor i have now be better then this one?

I have a AMD Athlon x64 X2 3800+ in my pc right now. Would a AMD Athlon 64 4000+ San Diego 2.4GHz 1MB L2 Cache be better then the x2? i know the x2 is dualcore, but i dont use anything that is optimized for dual core. and the other processor is faster. the processor im asking about is only $60 now. here is the link. http://www.newegg.com/Product/Product.a ... 6819103037

Keep the dual-core. For $23 more you can get:

Even if your programs aren't optimized for dual-core yet, Windows still does some of its own multi-processing management. Seperating processes between cores to balance the load.

that does seem like a good deal, and i can afford it, but would it be worth the 83.99? or should i just stick with mine? the reason im asking is i have the 3800 dualcore and my friend has a 4800 dualcore and his games load a bit faster, but i dont think its worth it. or is it?

i remember when the 4800 was like 400 bucks man

Ha ha, yeah, I bought mine for $300 and now its like $80.

There are no more new procs for 939 - so I would say go for it unless you plan on building an AM2 machine.

For < $90 you should see a nice bump.

Then you can sell your old proc and Ebay and get back like $15 or $20.

I ended up buying and AMD Athlon x64 X2 4800+ for $80 because the pins where a little bent (looked at picture before i bought and had a return policy). But basically I fixed it and got a never used processor for $80 that costs just over $200 brand new. The performance is great, Battlefield runs perfect now on all specs up.
