Guideline: Gaming-PC for your budget!

[Hitman]

So uem. What if we have €5000 to burn off? 

Then you must be simply retarded - go buy at Alienware then, where you pay around 2000€ just for the name.

For the 1st one, if its supposed to be a budget build, why would you not save some money and use only 2GB of RAM and then use the extra money to get a better video card.

4GB RAM cost 21€ here - 2GB 14€.  You wouldn't get a better videocard with 7€ more budget - maybe an 9600GT with 1GB instead of 512MB - but while only a very low percentage of games actually use more then 512MB,  the higher amount of RAM seems better for me.

For the last one, if your SLI'ing...id rather a Corsair PSU

The Enermax PSU is better (its 80+ BRONZE specified while the Corsairs are just 80+, and it has more connectivity options, + it has better overvoltage protections, which can be useful if you fuck your PC up while overclocking, and it has 75Ampere on the 12V rail while the Corsair just has 52A)
