New computer

[FlawlessHappiness]

Hello people.

I don't know if any of you have discovered the game "Planetside 2" but it's really cool.
It's a first person shooter game.
Enormous map.
Huge amount of players.
3 races.
and vehicles.

Oh yea, and massive lag for me...

So I though, now is the time to get a new computer.

My laptop is 3 years old. It has 4 GB RAM and 2.2 Ghz..
I'm don't really know anything about processers and such, but it isn't that good anymore.
If i install the newest Windows Update pack to it, then it won't accept my mouse anymore.
It just denies the drivers and denies that it is plugged it... (I tried different mouses)
So i can't update my windows anymore..

So now is the time to get a new computer i guess...

I found this: http://www.sharkgaming.dk/value-madness.html
Looks good to me, and a very good price.

Yes, the site is danish, but you should be able to read the stuff inside it.
Do you think it's good enough?

Sometimes in Planetside 2 i have a framerate drop to 0.5 FPS... or at least very very low. Cannot control.
I usually play games like L4D2 and, yea amnesia (Mostly with settings on low or medium).
But yea, PS2 is a heavy game...

So what do you think of what i found? Should i buy it?
