What would be the better choice, to buy a whole new higher end card to replace my current single 5770, Or to buy another 5770 to dual? Would it be near as powerful as higher end cards? and if not, what would be the difference? and im going for affordability, but it lasts me a long time and i can still play games on ultra.

More about : dual 5770 newer card

2 5770's would be about the same as a Radeon 6950, which I would say it pretty good. They are pretty cheap, but make sure you have the power supply for them. Maybe some HIGH QUALITY PSU around 700W.

Thanks, great answer :)  One other thing, im guessing my current AMD Phenom II X4 955 will probably ruin the point of upgrading my GPU? Or would it hold its own? And if not, whats a good replacement for it?

Thanks for the answers, I just have one more problem (I swear). I'm trying to find the voltage on my PSU, but i see no voltage. Just a barcode with some numbers on it and embedded letters. Any help how to find the wattage?

sounds like a cheap generic psu and would not be good to use for 1 card let alone 2.

I would really consider upgrading it to something more reliable.

Nope, Looked all over the dang thing, and all there is is a barcode. i googled the codes on the unit and i find nothing of interest.


Have you opened the case and looked at the PSU on the inside? If there isn't any sticker on it anywhere then assume it's junk and upgrade it. Alternatively, lookup your computer on its manufacturer's website and see what it lists as the PSU. A retail bought quality PSU will always indicate its maker/model at the very least.

Are you sure your mobo will support Crossfire? Make sure of this. Post your full specs when you can gather them.

I was wondering that myself.

Motherboard: MSI 770-C45
CPU: QuadCore AMD Phenom II X4 Black Edition 955
GPU: ATI Radeon HD 5770 1GB

Btw, PSU says antec, Guess ill try to find it on the site, but it probably is low wattage

The size of the PSU would help with the decision making. Antec is quality and if you have a 550-600watt you could crossfire but smaller then a single card like HD6870 or HD6950 depending on size would be good upgrade.

go with corsair psu, they are the absolute best [ my opinion ]. upgrade your psu either way. shortage of current can mess up ur rig. especially if u use crossfire or a high end gpu. [ 6900 series ] my corsair 750w tx is enuff to run a high end card or 5770 crossfire. but yet i will still upgrade it to be safe. besides, u will always use back your power supply depending on which wattage and brand u buy. its like a never go bad investment. if u can afford it, i will suggest corsair 1050w or 1200 w. if not corsair any around that wattage with good quailty. :] its a win win either way.

Well, I think you could still run something stronger but it depends on your exact PSU. Antec is a good name but you need to find the model/rating on it to be sure you have enough. Not checking could cause damage to your system. Your CPU is still great, I wouldn't trash the whole system, just figure out what Antec PSU you have and then you can figure out what you can put in.

a 6850 barely uses more power than a 5770 but offers about 30-40% more performance. might be an worthy upgrade without worry.

I say wait for the 7800 series to come out. Too bad about not having a CF board :p

I would personally prefer a single, more powerful card than crossfire anyway, I don't like waiting for AMD to fix crossfire issues that pop up every so often. coming from a dual 5770, I replaced them with a 6870 and will stick with single GPUs for now.

Most games that dont have dual GPU support are old enough a 5770 can max out anyways.

You can get a second one for about 100 clams and not spend the 230 on a 6950.

I feel like im leaning towards just getting a single card, considering i cant crossfire anyways, and i would have to upgrade everything, but the decision is what card. Would now be the time to upgrade? Actually seems like a bad time, considering the 7970 is so expensive right now. I guess my question is, should i wait a while to get a newer one, or should i go ahead and buy a 6950 or 6970?

Just love these posts where people read benchmarks. No, they are not about the same. The architecture of the cards are different. the 6950 by a long margin...... however, what games at what res/monitor ? This will determine what card you should get. and when looking for a ps forget the watts and find something with enough amperage to run your system efficiently.

5770 crossfire is about as powerful as a 6950. you can check the benches yourself.

crossfire does have issues tho.
