Depends on you and your need man... !!! so please tell us what exactly u would do with your system ??

Well AFAIK no 939 socket motherboard supports DDR2 RAM. In this case u have to upgrade all of ur components including Processor,Motherboard & RAM.
And the answer will be INTEL Core 2 Duo.Ur budget is 25K and u will also get something when u sell ur System then roughly u will be having 30-32 K (min)
In this case u can have a smooth config. like this:
E4300 =5050/-
XFX nForce 650i Ultra =5550/-
Seagate 250 GB= 3000/-
Transcend 1 GB 800 Mhz = 2650/-
Samsung 18x DVD - Writer = 1675/-
PowerSafe 500W Silver SMPS = 1900/-
Cabinet = 1100/-
XFX 8600GT = 7700/-

Total = 28625/-

U can also add an extra RAM same one.

Thanks Keith,
Actually I wont replace my existing hard disks,If i go for full upgrade then it will processor,mobo,graphics card and RAM.Thanks for your suggested configuration

Well at this point u can save 3000/- and u can go for 8600 GTS for 11000/- approx. which is a better card than 8600 GT.
