Upgrading HP Pavilion a1320n?

[Zaya da slaya]

Hey guys, I'm split right now between selling my xbox and getting a newer, awesome computer (Other thread) or just upgrading my current one.

I have an HP Pavilion a1320n (Thats what it says atleast) and I've been defraggling, setting prefrences low, ect, but I want to be able to run games like Warcraft 3, Halflife2, and TF2 at top or near-top res.

Any idea how I would go about this? The only time I've ever opened up my comp was to clean dust, but I think I could handle removing and inserting things like RAM, ect.

So, is my computer upgradable? Would I need a new power supply? Could I just get some more RAM? I know theres a computer nut out there who could answer my questions! =D

EDIT: I'm going to upgrade my current PC.

What is your upgrade budget, assuming you decide to upgrade your HP?

Well, I'm looking to not do too much, just making me able to play higher res stuff, so I guess $100? Or is that not even enough to do anything? I really don't know, but cheaper = better.

You could do pretty well for around $100. Give some time for me or somebody else to dig something up.

as I said in another thread about this 4770 that Rohan linked, this is the best low power gaming card ever made...

no other low power card can touch it, it can overclock to rival the performance of the 4850....

That looks pretty nice actually...(The card)but I honostley would have no idea how to switch them out or put this one in, so I would need some guidance on that, no need to break my computer! =D\

EDIT: Does this computer I have come stock with a video card? I want to know how much of an improvement it would be buying this card. THANKS!

easy as it looks, though you need to really check out your video card clip first, because some are different than the one shown

Dude thanks a ton that looks so easy! I could do that for sure! Do you really reccomend that one? Anything else that might be better for what I need?

(High res for warcraft 3, TF2, ect)

EDIT: Also, I talked to one guy and he said I might need a better power supply or something? Would I? Or could I just run stock with a better card?

I picked that specific card because it wouldn't need a 6 pin power connector from the psu, I figured that you wouldn't want the extra cost of a psu on top of the video card...

but if you want to spend the extra a decent psu in the 450w-500w range will add an extra ~$40 to the cost of a more expensive and powerful card...

So basically I would be able to slip that card it, with no extra cords or whatever, for ~$100, and my computer would be able to handle higher res games with no side effects?

EDIT: Also, how much overall better would my comp be after installing this? I currently have ATI Radeon express 200 or something
