What can the GT 630 2GB run?

BF3 - No, low settings in single player.
Metro 2033 (Last Light)??? - No - Probably will not be playable at low settings.
Crysis 3 - - Probably not even at lowest settings. 1080p is just too high for that GPU.

Probably not well at all...

Lowering the resolution of a game (or in general) past the LCD's native resolution causes de-interlacing and makes it look like crap, too

If you lower the resolution to 720p. Then all of those should be playable at Medium settings with low to no AA.

You not only have to worry about the size of the case; the PSU (300w) in that is going to be a problem as well

Wow you overpaid for that thing. Yes you can upgrade the GPU , you will need to upgrade the power supply too unfortunately since 300w is not near enough.

Tell your dad he is being an idiot. LOL (not really obviously)

Persuade him that prebuilt PCs have inferior components and let him read this : http://compreviews.about.com/od/general/a/BuildvsBuy.htm

Your dad is a typical technophobe.

OK buy it from here. They build it for you and handle all warranties. Its not as cheap as when you build it yourself. But its still much better than HP junk.

If your dad makes you get the HP you would need to upgrade the PSU to add a better GPU but in that case try to go for a GTX 660 or GTX 660ti or a AMD HD 7870 they should all handle those games good at 1080p.

If you *have* to have a prebuild, I've had good luck with CyberPower. The best I could do (with VAT) is 633 pounds and still have quality components. The GPU is significantly faster than the 630 and you have plenty of quality PSU for a faster card later.

You could drop down to a CoolerMaster 550W PSU and 4GB total RAM to get you under 600 pounds. I wouldn't recommend it, but it would be better than no PC at all.

EDIT: Forgot about AMD - Novuake's build would be good and get you under your limit.

J_E_D, dont you think having a better graphics card and getting an AMD Quad instead is better than getting an I5?

Ya, mo GPU is mo betta. I'm just hung up on i5's... My bad! I'd get Novuake's build over that one you linked from Amazon (or mine /cry).

Nvidia GeForce GT640 graphics card on that?? Its not good. Anything under GTX650 is not meant for gaming.
You also do not know what quality components that build comes with. Which is VERY important. PSU especially.

That would defeat the point of saving you 100$. LOL. Cuz if you wanna game that is gonna have to be upgraded, which will cost MUCH more than 100$.

Besides, other component quality needs to be considered too. That PC may not even be designed for a larger graphics card at all.

Depending on what the money conversion is, you can find a nice xps 8500 for about 750 us dollars. I was in the same situation, but I chose the xps and stuck a 7870 in it and it runs perfectly. Also, 460 watt psu in the 8500 vs 300 in the hp.

This is true, and on top of that Dell PSUs are much better quality than HP.

Don't know if anyone has mentioned this yet, but you could run an AMD HD 7750 on a 300w PSU.
I have a 7750, and I play Metro Last Light on high settings, Battlefield 3 on Ultra (no AA) and Bioshock Infinite on Ultra (without Alternate Postfx) at 1080p resolution. Each one of these games never drops below 30fps for me.
However, I've overclocked my card by 20%, which you (and indeed anyone) should do anyway.

Seriously though, your father should reconsider his preferences when he'd rather force you to buy a terrible pre-built rather than allowing you to take up the mantle and build one yourself. Hell, my dad encouraged and taught me to build my own computer at the age of 14. The result? Better bang for buck than anyone could ever hope to achieve when buying a pre-built and I learnt a skill which I think is pretty essential, providing the current Economic climate. I hope you managed to persuade him, mate.
Good luck.
