Getting a gaming computer

[STC]

Hey i am working on a gaming computer....dont want to put all the parts together my self so i am going to buy this computer http://www.newegg.com/Product/Product.aspx?Item=N82E16883227241

im looking at the computer specs and it says it has a bunch of pci slots, but it also says right now it has a radeon hd 5450 PCI Express 2.0 x16...does that mean there is a PCI Express 2.0 x16 slot open if i take out the radeon 5450?

i read the reviews on the computer, and it seems to be pretty good save the video card, but its good enough for now, so i will upgrade later in the future....what video card would i want to upgrade with? i was thinking this one:

this will be my second time buying my own computer...first time i tried buying a cheap gaming laptop....with a radeon x1200 graphics card.....LOL was a fail, and wasted 800 dollars....
hoping this time i will get it done right!!

thanks

first of all, how much money are you willing to spend on your computer?

wanting to spend around 550....willing to go to 600....but really dont want to spend too much! but if u can find me something catchy i might fork out another 100! :S

tempted to get a loan and buy this:

but last time i spent that much on a laptop it turned out to be sucky....how can i be sure this will be awesome?

If you are looking to spend close to $1,000.00 for a gaming machine you would be much better off getting a desktop as you would get more for your money and it has a greater possibility of being upgraded in the future.

Laptops are generally not good for gaming unless you either want to spend big bucks for one or you only play simple games.

what do you really want? a laptop or a desktop pc? And what games do you want to play? Then we can find a computer for you that will do what you want 

Your first link  (the newegg one for the iBUYPOWER computer), is a desktop pc.

However, then your second link (the samsung pc from bestbuy) is a laptop.

I personally think, a laptop or PC that has decent enough performance for what you want it to do is sufficient, although it would be nice to leave room for upgrades if you think you'll want to do that in the future too.

ok sorry i got distracted by the laptop....desktop is definately superior and more cheap so i am going with desktop.... my plan is to get the desktop from my original post for gaming...but i heard that graphics card isnt the best....so what should i upgrade it to? and is the 480w powersupply good enough cause i dont want to upgrade psu too....maybe can yall find me a desktop in my price range i should buy?
