need a new comptuer

need a new computer give me some ideas on what to get, my budget is $800, a little bit over no big deal.

core i3/i5 not sure up to you (Intel)

umm 4gb ram a must

windos 7 basic

1T.B get lower to save on money if you want I probs will never fill the 1.5 TB I have in mine

get ATI card ummm mabes if you can but would probs ruin budget get a 5770HD, or for something lower try the 4870HD
Depends if u want to use dx11 in future

um what else get probs a 500-700w PSU I like corsair but apparently they suck.

Use generic mouse/keyboard/whatever monitor u can find.

Whatever the cheapest case they have that has got a good record doesnt matter if ugly or not.

I actually got my PC on ebay at this store: http://stores.ebay.com.au/protuned-systems

But always be careful when u shop online.

P.S Get a desktop if you want unless u plan to use a laptop for uni or something.

Scorch or someone heaps techy would be best at helping you choose wat u need.

Remember to get a pc that u NEED not one that u WANT.

Cause I ended up spending heaps on a PC that I didn't really need to I mean its nice being able to play high settings on latest games but yeah I mostly play M&BW so there u go.

For a cheap bang for your buck computer, you will need to shop around and check prices as much as possible. Here is a good list of parts to start as a base (these can be changed up significantly, its just a blueprint):

preliminary reccomendations:
Case: Any cheapy under $100, thermaltake/antec usually good.
Mobo: Gigabyte P55A-UD3 ~$130
CPU: Intel i3 550 ~$172
RAM: G.Skill Ripjaws F3-10666CL9D-4GBRL (2x2GB) DDR3 ~$135
HDD: Samsung SpinPoint F3 1TB HD103SJ ~$89
GPU: Sapphire Radeon HD5770 1GB ~$199
PSU: Corsair VX-550 Power Supply ~$106

Total: $890

If you already have a good PSU with at least 600W of power (I say 600 because I don't know what brand, so I can't tell how efficient they are), then you won't need a new one, however that corsair one will fill your needs.

If you really want a powerful computer but extreme value for money, you will have to spend more. Here is a very good Uber Value computer:
