I currently have a Nvidia GeForce GT 220 graphics card, but I'm looking to upgrade it. Here are my computer specs:

OS: Windows 7 Home Premium 64-bit
Processor: Intel(R) Core(TM) 2 Quad CPU Q4800 @2.66GHz (4 CPUS) ~2.7GHz
Memory: 8GB RAM
DirectX: DirectX 11
Video Card: NVIDIA GeForce GT 220
Power Supply: 450 W

Here are the cards I'm considering:


Which one of these cards should I get? Also, how would I know whether my computer can handle, or even hold these cards. How can I make sure?

Same price as above cards, performs the best though.

If it handles a GT220, it'll be fine with the 5770, which can run off of a 450W PSU with no sweat.

How do I know if it will fit in my computer? And I live in Canada, so I can't purchase anything from

Of the four video cards I have listed, how would you rank them?

HIS Radeon HD 5770 1GB GDDR5 PCI-E w/ DVI, HDMI, DisplayPort
Sapphire Radeon HD 5770 1GB GDDR5 PCI-E w/ Dual DVI, HDMI, DisplayPort

Are the same performance.

Have roughly equal performance (5750 being better).

Of the 4 cards, the Sapphire one would be the best.
That one, if OC'd would be the absolute best.

the MSi one is good

Is a 450 W power supply enough for the 5770's? Do I simply install the card into the PCI slot, or do I need to connect it to an external power supply?

You simply install the card into the slot, plug in the 6-pin PCI-E power connector (if your PSU does not have one, simply get a 2x Molex -> 6-pin adapter ($5) ), and fire it up!

Is my PSU strong enough to handle both of the 5770's?

Not for two of them, but for one? Yes, it'll work just fine. The HD5770 doesn't use more than 70Watts of power normal gaming (Crysis, etc).

The one you just posted is very inferior to the HD5770.

Can you post your motherboard's model? If you wish to find it yourself, a PCI-Express lane looks like;

Looks like you have 1x PCI-E 1.0x4.

I would not put more than an HD5670 in that.

So I should I get the HD5670 that I posted above? It also requires one X16 lane graphics slot available on the motherboard. I could post up more info on my computer if you need.

Oh, so you do have a PCI-E 2.0. Note to self...not every site has the correct information...

In that case, you'll be perfectly fine for an HD5770.

I have heard that the HD5770 takes up more than one slot. Do I have enough room for it? Also, should I measure how much space I have in my computer before purchasing the card? I believe the HD5570 is around 8". Also, I'm afraid that my 450W PSU is a no name brand since I did not custom build this computer. I bought it from bestbuy. Do you think the my PSU actually has an output of 450W or something more like 300W?

Here is some more information:

This is the PCI-E 2.0:

Of my three PCI-E's, only one currently has no device.

You're fine. It uses no more than 70watts of power during gaming.
April 24, 2010 5:58:29 PM

And I don't need to remove anything (other than my old card) to make space?
April 24, 2010 6:40:17 PM

You should be fine.
Just swap the cards ad install the drivers and it should work.
