Gaming Hardware update#1.1

OK for all those guys who have a tight budget, here goes:

CPU: AMD AthlonII X2 550 Black Edition OR Intel Core i5(coming out soon, still don't know the price range, but I'm guessing that it would be an Intel competitor for the athlonII)

MOBO: Any AM3 motherboard from Biostar or Jetway, both are cheap and good.
For the Intel CPU I'd suggest waiting for the new i5s to come out and then see if there's any cheap motherboard out yet. For the time being, MSI Eclipse is the cheapest and the best(its not very cheap though)

MEMORY: Since AMD CPUs still don't support triple-channel DDR3 memory, you'll have to go with either a 4GB setup or a 2 GB setup. And.........since you're in a tight budget I think you should go for either a 4GB GSkill F3-12800CL9D-4GBNQ (65$) or a 4GB Crucial Ballistix BL2KIT12864BE1608 (40$)
Intel owner's have better DDR3 options. They can choose between 3GB and 6GB. For the budget people, 3 GB is a better choice. A patriot 3 GB PSD33G1066KH is the best choice for entry-level gamers.

Video Card: This is the most important part. For entry-level gamers, there are a wide-selection of ATi and nVidia cards available. I will tell you the cards which offer the best value for money.An ATi HD 4770 512 MB GDDR5 card is most recommended because of the GDDR5 memory advantage over other video cards of its price range(110$). nVidia's GTS 250 is the primary competitor of the 4770 but it has GDDR3 memory which isn't as fast and it costs around 125$.

HARD DISK: A 640 GB Seagate or Western Digital will do quite nicely.

Keyboard/Mouse: Since you're an entry level gamer you don't need very cool input devices. You can buy a normal wireless Logitech keyboard and mouse combo.

Cabinet: Your best buy would be an Antec 900. Its a great mid-tower cabinet with decent cooling.
