Hi, I have started a new debate. The best budget gaming PC on which you would be able to play DOOM 3 with decent FPS. The configuration of my preference is : Processor : AMD Athlon 64 3200+ (Socket 754) This Processor promises to be future proof and easily leaves behind Intel Pentium 4 3.2 GHz Northwood and Prescott both. This processor runs on x86-64 extensions to operate 64-bit programs (although it doesn't seems that most software developers are interested currently in 64-bit apps).it runs on 2.0 Ghz and can be overclocked nicely till 2.6 Ghz if u have a overclocker friendly motherboard.its cost is Rs 10,000. Motherboard : If u want a very feature rich motherboard, go for a Gigabyte one i.e. Gigabyte GA-K8NSNXP, its good to overclock as well. With IEEE 1394b and dual lan and gigabyte's propetary features like dual bios, DPS K8 it leaves all motherboards out of race if you go in for AMD 64. This motherboard cost you nearly Rs 12000. Another feature rich motherboard is MSI K8N Neo Platinum. it has good overclocking potential while remaining in budget. Featuring Dynamic Overclocking it can overclock your processor on the fly.This motherboard would cost you nearly Rs 9000. Or u can go for DFI LANPARTY UT nF3 250Gb if u are going to buy a transparent cabinet. With tons of features this mobo has some really sexy features including UV lighting and lots of overclocking capabilities. It may cvost u nearly 10000-12000. RAM : Buy a PC3200 DDR400 SDRAM with low latencies. A 512MB stick would cost u 4000-5000 depending upon brand. Kingston, Crucial or Corsair are good brands. Graphics Card : Go for nVidia GeForce 5700 Ultra with 256 MB DDR2 Ram. An MSI build would cost u Rs 8000 but will give u blazing performance. Hard disk : Wide selection creteria prefering SATA hdd u can go for Samsung to be in budget, for western digital or seagate or maxtor. all are good brands. an 80 gb would be enough for anybody. but u can always go for 120 gb or 160 gb but i would prefer u to go for two 80 gb hdd and raid them (in raid 0) as all motherboards mentioned above support raid. DVD writer: best dual layer dvd writer within budget is Lite On 8x Dual layer DVD writer SOHW-832S, which would cost u nearly 6700 bucks. Cabinet : An Antec one would be preferred over any other brand. With plenty of space inside the cabinet their build quality is best. Antec Performance Plus 1080 AMG is my choice which costs rs 6000.
