Hi I just bought and 8800 GTS 512 BFG, and now my games run fine all on settings to high in 1280*1024 resolution, but sometimes it came inestable I get some glitches while gaming, and the card itself make a lot of noise when Im playing. I have a PSU of 450 watts it came with the case ... so it can be the problem?? do I need to buy a better psu?? and of how many watts??

I think you should get a better PSU. 550W to be safe.

Ok, but wich PSU?? I don know which to buy, do I have to look for some especial specs? or what?

Antec is a good, cheap brand. Go shop around, they come in pretty cheap.

Just picked a random one.

Other good brands are Corshair, OCZ, Silverstone, Enermax...too many to list.

Ok but do I need for some speccial specs like ... i dont know but how i know if it fits to my case? and all the cables and other stuff? sorry but Im not very knowledge about it!

This is probably one of the best websites to give you information on choices. For your card...I would check out minimum 550 Watt...but at least 600 to be safe

Some of the better middle level PSU's

Thermaltake
Corsair
OCZ
Seasonic

The only thing I can tell you about what to avoid, comes from reading people's problems with Rosewill. They are cheaply made. I also understand that some of the Nvidia GTS 512's might have an issue or two with Antec PSU's...otherwise Antec is pretty safe...

Well, what's your case? If it's an average sized case, an average PSU should fit it.

Most PSU comes with a 20+4pin connector, so even if your mobo takes only the 20pin, it'll work out fine.

Ok thanks ! but the problem I have, I mean the glitches and all that, it is 100% sure that is a PSU problem?

Even if the PSU isn't the problem, 450W just isn't enough. At the very least, go 500W, but to be safe go for 550W. If the problem pursues, it's probably something else.

Oh and please tell me your PC specs and what sort of glitches you were having.

well the case I have is very simple and ugly jeje:

thats the case I have, I think!, well they look pretty similar almost identical, but the one of the link has 350 watts and mine ies 450.

My specs are:

AMD 4200 OC to 2.4
M2N32 SLI DELUXE Wireless edition motherboard
2 GB Kingston 667 ddr2
Windows Vista 64 bits
8800 GTS 512 BFG

The problems I have is in games, for example,I can play bioshock with all high, but sometimes the camera stopped like 1 - 2 second, and some glitches like that, on almost all the game I have 60 fps with vertical sync on (my refresh rate is 60 hz) but sometimes it goes down to 30 fps.

Sounds like a PSU problem. Not enough power produces stuttering in games. Go change it.

Now that I think of it, you're pc is a bit unbalanced. I'd recommend you OC your cpu more after you get a better PSU.

Ok thanks! I have tried oc my cpu, and I reached 2.7 ghz, but it turns too hot, it easily went until 65 C°!! so I´ve turn it down until 2.4 and now the max them it gets is like 50 C°.
Will a better psu make things easier for overclock my cpu?

Oh yeah.

I'd recommend this cooler: http://www.newegg.com/Product/Prod [...] 6835887011

It can match the best air cooling for less. Problem is, there's complaints with it when using it on AMD systems.

Oh my god it looks huge! would it fit in to my case? I also was looking for some cpu heatsink and reading reviews I was thinking to buy this :

Zalman = overpriced. No don't go for that, unless it's on sale.

mmmm but I´ve heard some good coments of it! well but any of them will fit on my case an mobo without a problem? sorry Im a noob!
