1. Unless you can get that HD 4870 dirt cheap , HD 5770 is the way to go ^^
2. The StealthXstream line is not 80+ certified: perhaps go ModXtreme or others?
3. What would be the resolution u game on?
4. Max budget?

i am getting that 4870 for really cheap approx 100$, from another country ^__^
1280x1024
max budget = 700 - 800$

^ Well then stick with HD 4870...
And as for the PSU, like batuchka said, they are not that good compared to the ModExtreme series...So change to the ModeXtreme 500/ OCZ Fatality 550W

And for that resolution though the 4870 is anvoverkill, but for that price its a very good buy...
And change the HDD to Samsung F3...they are slightly faster and more reliable compared to the current Seagates...

Also if you have budget left, I would get a Crossfire/ SLI mobo with a slightly more powerful PSU so that it opens up the option of going crossfire just incase you switch to a higher resolution monitor...

For the Samsung F3, it's 1TB. I did not plan on need 1TB of space, but is it a must to change the HDD for better performance?
I don't plan on going crossfire and also I'm going to be sticking with this monitor.

^ Well there is a 500GB F3 too...
And more than the performance, the reliability is the main concern here...

Well why not the UD3 ?? It is cheaper except that it doesnt have eSATA, but has all other features of the UD3P...

And again it would be better if you invest in a better PSU as those can be reused for future builds too...

the OCZ Fatality looks good, but I can't seem to find the F3
Could you link me the F3 and the UD3?

I also want to know about the heatsink, is it a good idea to go with the one my core comes with, or to buy a better one?

^ Will you be overclocking ? and or do you want to try overclocking ?
If Yes, then get an aftermarket cooler - A cheap and a good one - CM Hyper 212+
If you dont overclock, then the stock cooler is fine...

alright thanks, I heard overclocking reduces the cpu's life, but makes it faster.
Is it a good idea to overclock?

Screw the i5. i7 all the way. Yea the i7 will get a little bit hotter but i5's are small and not as much value as 1366.

^ Well it would depend on the amount of overclock that you do and how you do it...
If you stay within the maximum CPU voltage threshold and the maximum operating temps of the CPU, overclocks wont affect the life of the CPU...
Say you overclock the CPU to 3.6GHz level with an aftermarket cooler like that CM Hyper 212+ and at stock voltages or just with minimal increase in the stock voltages, the CPU would still last long, maybe even longer than your next PC upgrade or rebuild ;)

is it possible to just OC with a stock cooler? Friends say there isn't going to be much more of a difference if i use an aftermarket cooler.

^ I dont think so...
Say upto 3GHz, the stock cooler might hold up, but anything more will result in overheating of the CPU...
This is the mistake that people do and the result is a fried CPU...
So now you get it why people say overclocking will reduce the life of the CPU ??? It is because people dont do it the way it has to be done...

I see, the 212 is great for it's price. I will consider overclocking. Is there much difference in speed though? The human eye cannot see the difference, but is 0.4GHz a lot faster?

^ Well yes it does make things go faster...you will notice mainly in tasks such as video encoding and such...But for general stuffs you might not notice...

Would a 650W PSU be better? Friend is recommending it. Higher W = ??? What does it do?

Would having a higher powered PSU affect OCing?

^ Overclocking the CPU will have a little effect on the power requirements...So if you have a good quality PSU say a 450W Corsair, It will still be able to handle that very easily...
the only major component that puts pressure on the PSU is the graphics card...If you go with multiple graphics high powered graphics card, then only you need to go with a higher wattage PSU - say 650-700W+

Say for any overclocked CPU - including i7 for eg, + HD 5870, 500-550W PSU would suffice...
