Worthwhile upgrade?

[celliott]

I currently have:

AMD Athlon 64 @ 3Ghz
2GB PC3200 DDR
X1800XT etc etc.

Considering upgrading to:

Intel Core 2 Duo E6300 Retail
Asrock 775DUAL-VSTA Motherboard.

Reason for choosing this board is that it supports DDR400 as well as DDR2, and looking at some performance charts there does not seem to be much in it.

Do you think I will see any noticible improvement at stock speeds? I use my pc mainly for gaming and also sometimes encode movies for DVD.

Also can I expect any overclocking from this board. From the specs it sounds like there is overclocking features but thats it like. Any rough ideas on what sort of clock I could achieve?

Thanks.

Sure thats a better option but I cannot afford a new £80 motherboard and new ram too which is why I am looking for something I can use my old ram with. There has to be at least a little bit of overclockability in this board?
