My budget is currently going up to 38000 Rs. (INR) i.e. about 800 USD.
Should i repost these details in the format supplied by yoyojam55?
I was planning to take the config tomorrow but will put it on hold till the weekend.
Need to get the config verified as i am myself a noob at it.
BTW, is the mobo fine? and shd i go for 2 GB or 4 GB of RAM?
and find out how much power you need. Then all you have to do is research on how much efficiency the power supply you are buying runs at and see if it has enough to meet your needs. Its the most important part of your computer!
As for the hard drive I prefer Seagates. I always have for home and enterprise use. I prefer their warranty, and I require it less than any other brand out there. 1TB for the price and I put 2 of them in there for a RAID.
Heatsink is all that is missing. I choose the Sunbeam Core Contact Freezer. It works good, and works good even with the fan speed reduced while watching a movie for example. I own one and recommend it. It is better rated than the Xigmatech you choose which is also good. The sunbeam is also cheaper.
This system is cheaper than yours and I think better. It comes with the Antec 1200 and Sunbeam heatsink so you can crank down all the fans while watching a movie and it is silent. you get a better video card. I also priced 1TB hard drives which are almost double the capacity of your 640GB.
Overall it's a cheaper system that has a way nicer high end case, and components that will beat your system in gaming. A great value price/performance winner.
The 4770 is better price/performance out of the cards you've listed, but it can be hard finding them in stock. The 4850 or 4870 are also great cards at reasonable prices. Both are better than the 9800gtx and 9800gt IMO.
