Need help picking out a vcard

Yes, you definitely can. You should be able to grab a 5770 and a good psu for that.

And this psu would be able to handle TWO 5770s, correct? What about anything in the 58XX family?

This ends up being $237 after shipping and taxes to canada. Worth it? Doesn't leave much room for a psu... Then again, I don't know if PSUs are even expensive or not compared to other components.
 
Completely correct; Electro-Static Discharge occurs. Just touch any bare surface of a conductive metal and you're set. I normally discharge again if I got up or moved a lot.

EDIT: The company could have been quite conservative with the wattage label. I'd have to do all the math to check if 430w of output is correct.

or like some companies they could've loaded the useless 3.3v and 5v rails to add wattage to the psu, useless wattage, but wattage for the label and "specs" that they can claim as output nonetheless...
 
^ That's probably a very common practice. Plus you have to account for PSU efficiency. Which I would assume is in the 70 percentile region.

The xxx edition is a good $20 more than the average 5770...it's good, but isn't that much more powerful considering you can just overclock the other ones.


This would be a great PSU:

54 amps on the 12V rail, and >80% efficiency. The 5000 series cards are all under 200W except for the 5970, which is ~300. Teo 5870's at 200W each (rounded up), plus 140W for the CPU, is around 540W. Allow ~40w for the rest of the system, and you're still well within safe levels.

You can really see the difference between this and a cheap PSU. The quoted 650W is for the 12v rail only. A cheaper brand would've partially added in the 3.3v and 5v rails and called this an 800W. This type of thing is more common than you'd expect. This Rosewill, for example, is rated at 550W, but the 12v rails combined can only provide ~430W:

So how about this card? This card, plus the psu you showed me, is $327 after taxes and shipping, I'm sure I can pawn off a few gamecube and ps2 games and make $30.

Now, I reeeally don't know anything about psus, besides wattage, and obviously, wattage can be very deceiving. Now, when you say the cards take up 200 each, plus 140 for the cpu, and another 40 for legroom, is this before or after the wattage efficiency factor? Cause the good one you recommended runs at 650w but at 80% efficiency, 80% of 650 is 520, which wouldn't be enough.

*edit*

Wait, is that 140w for MY cpu or ALL cpus? Cause I won't have this one much longer.

those are just theoretical numbers, a system very rarely, if ever, draws it's total theoretical maximum draw all at once, also, this Antec 620w is a good psu and is a little cheaper, plus though not rated for crossfire, some people are running crossfire on it anyway, it's a good psu from a reliable distributor that backs their products about as good as anyone if it fails, any brand psu can be a dud, even the best brands sometimes, this is one of the brands that is usually more reliable than most others...

it's also easier to run crossfire on the newer cards because of the power efficiency improvements...
 
edit: Silverstone is a better brand than Antec...they're up there with Corsair.

That card is fine. Sapphire has arguably the best build quality available.

Most cpu's aren't 140...not even yours. I was using conservative measurements.

Going by the standard TDP ratings, your current cpu, plus two 5770's, would be 281W.

Ohhh... heh :S This right here is why I ask obvious questions, cause that's a real curveball to me.

So here's my final question (I think, lol quite a thread this has been), can that 5770 run on my current 300w? If not, can it run on that 430w I mentioned? You said it woulda been overheating that wrecked my card from 5 years ago, not the PSU, soo...
 
Now that I look at it, the 300W only has 216W on the 12V rail. A single 5770 would take up half of that, and the rest of your parts would take out another big chunk of it. Cheap psu's tend to fail if they're run upwards of 75-85% for too long, especially if they aren't at least semi-new. Obviously you won't be running your system at max power all the time, but I still wouldn't chance it.

You said the 430W one was 12v/18A as well right? Again, that makes 216W.
 
Get the vaporX 5770 if you can. It has a much better cooler and somewhat higher clocks.

If not, be sure you get the V2 cooler (egg shaped one) as it is much cooler than the V1 (batmobile one)
