9800gt green or 7750.

A lot do, as it's hard to isolate the power draw from individual components. In the description of the graphs it states that it's measuring 'Total System Power Consumption' - make sure to look out for that in the future, or you may think cards are far more power hungry than they are :lol:

If you're on budget, I would, however, recommend buying used. I am always willing to pay around £300 for my GPU, but if you need to keep it as low as possible, I'd get an used GTX 460, or something like that. You'll get much more bang for buck. Surely someone you know will be upgrading, ask them to sell you their old card... I have just sold my old GTX 570 to a friend of mine for £140, we both benefit from that, I would get less on eBay and he would pay much more for new.
And as others said, yes, get a new PSU, RIGHT NOW!!

I have some savings, quite frankly enough to buy a decent machine, but not enough to buy what I want.
I am aiming for 3570k, 660ti, ud3 z77 gigabyte mobo and 650/750 Corsair/Seasonic PSU. Right now I am using old computer that isn't very good for gaming. I don't want to upgrade it too much, as in a year or so I am going to put together brand new machine. So investing in new components just for a year would be waste of money. I am only thinking about upgrading my GPU as that green 9800gt sucks. The only choice I have though is 7750 as other cards are too power hungry and if I decided to buy them I would have to upgrade my PSU as well.

To sum up the only question I have is:
Am I going to see any significant difference if I upgrade y zotac green 9800gt to Gigabyte 7750?
I've seen some benchmarks, but still it's good to ask people who know a thing or two about PCs.

Yes it would be a big difference but what were saying is that even if you do just get the 7750 you should still be upgrading your psu

Why do you think so?

7750 is less power hungry than that 9800gt I believe.

This PSU is not one of the best, sure, but it still works fine. It's 3 years old and I never had any problems with it.

 

[seumasbeathan]

I just would not trust an unbranded psu

 

[Josh Weston]

In honesty, you'd probably be fine.
Even if your entire PSU was only powering a single LED light, we'd advise you to upgrade it, just because those cheap things can go up in smoke in an all too literal manner.

I've learn the hard way long time ago.. Kept upgrading my entire PC and ignoring the PSU (any PSU will do the same job, I thought), overclocking, tweaking just so one day during a longer gaming session it just blew up. Everything was gone, and it wasn't a cheap machine back then. I always get branded PSU with some power reserve ever since. Your choice now... If I were you, I'd upgrade the PSU first, and then started buying another parts. Get a PSU and a GPU, and you might not even need to upgrade anything else..

It's not unbranded. It's mustang! Hah, probably not the best PSUs out there but it isn't uber terrible too. I am fully aware PSU is one of the most important component, and therefore knowing the limits of my PSU I am not going to stress it too hard. That's why I am only considering 7750 and not any better card. It should actually draw less power than my curent GPU.
