Mother board upgrading help needed... urgent

[eureca_eureca]

i am planning to upgrade my pc .

the config is

p4 3.0 ghz ht processor (775 socket)
dg 101 ggc mother board ( very bad mother board )
256 ddr ram

Would this processor work fine with ddr 2 rams and new mother boards , i also need a mother board with serial port , cos i need to run billing software at my office which need serial port for printing in dos format ( my software programmer is not likely to make any change in near future )

if the processor is not compatible please suggest me a good combination

Budget
proc+ ram + mobo under 8 K Rupees


Please help me , i need to do shopping soon

Thanks

you may need to look at G45 motherboards. But it's difficult to find boards that support DDR as DDR2 and DDR3 have become mainstream now.

Would my proc support ddr 2 ram ?

No serial port for this mobo , its a must for my dot matrix dos printing

2.5 is a good price i think !
