Hi Guys,
I am currently planning to build one gaming, enough to play all the recent games in decent resolution (1680 * 1050). My total budget is around 40k - 45k INR. Here is my config. Please post your suggestion guys
Intel Core 2 Duo E8400 Rs8750
Asus P5Q - Pro Rs8400
Transcend DDR 2 800 Mhz - 4 GB Rs3700
Seagate 750 GB (32MB Buffer, SATA 2) Rs6000
Zebronics Vivah (400Wpsu) Rs1450
Palit HD 4850 = Rs13000
Logitech Keyboard and mouse set. Rs600
(All prices are according to Chennai market)
So the total is 42k.
Is this config ok. Do i need extra power supply and cooling. This is my first build, help me out.
