Seems like it's going to be a bit of a niche card with it being caught inbetween cheap entry level cards and slighty more expensive mid range cards. But still looks quite good for the price.

The one in the picture is for a normal PC (PCI-e slot). What kind of 250w PSU do you have? Is it a factory one from a pre-built PC?

According to those charts, and I'm assuming the measurements are taken from the wall (I believe that's how the "kill-o-watt" works), it appears to be a low power consumption video card. If it suits your gaming needs, it should be fine.

From my experience, your PC will freeze or shutdown while gaming because the video card couldn't keep a stable supply of power. Then you know it's time to upgrade the PSU.

I forgot to mention that i'm in Mexico, and here is difficult to find good deals.

This is the one i want to buy, and my concern about the size is because all 5570 that i've seen here are bigger, take a look

Good point. You will need a PCI-e slot to use any new video card.

I just bought the HIS IceQ 5 H577QT1GD Radeon HD 5770 Turbo 1GB 128-bit GDDR5 on Newegg for $179 bucks and it is awesome. I tried 3dMark Vantage and got good scores so thought I would try the Ubigine Heaven Benchamark also kicked butt just started playing Chrysis Warhead Farcry 2 and S.T.A.L.k.E.R Call Of Pripryat and I can't seem to find a game to throw at it that it can't handle.I would recommend it to anyone who wants to step up there game just a FYI hope you got a nice case cause this card is big and it takes up two PCIe slots but the nice thing is it has a grill that will push hot air out so keeps the case nice and cool.This is my rig
