Would I see better performance browsing Anandtech? Thats what really counts.
How about if I overclock it?
Crossfire 2 of these, that should give you about 20% more ad performance
Oh man, I never thought about going Crossfire for better ad performance. Thats brilliant, should I upgrade to a 2500k and a 512 GB SSD also?

This thread went to Failtown pretty quick and seems to have blown a tire there.
jump to crossfire and you can surf anandtech forums while they do maintenance.
XFX Double D FX-785A-CDFC Radeon HD 7850 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
The Dual-fan edition for $249 w/fs.
Thanks for sharing this.
Here is what I've concluded about this card from reading newegg reviews and the post about this deal on slickdeals (I can't confirm the legitimacy of any of these things, I'm just sharing what I've read)
- The clock limit of the AMD drivers is normally 1050/1450 with stock voltage, but using the latest version of TriXX software from Sapphire, it is possible to tweak the voltage to 1.3v to allow you to break that limit
- It includes a 2 year warranty, but if you register it on the website within 30 days of buying it, your warranty becomes a lifetime warranty
- No idea if this happens to everyone, but as per a newegg reviewer: "Cons: Experiencing stuttering issue in Diablo 3. This is Blizzard's problem and something they have not addressed at all (including zero acknowledgement) since release."
- Mentioned by two people on slickdeals: "benchmarks show that the xfx 7850 models run hotter than msi, sapphire, asus"
- This card requires two 6-pin power connectors, allegedly because the XFX brand uses the 7870 board. Most other brands only require one 6-pin power connector.
- People praise this card for great performance for its price.
It has been said that these cards could all become less expensive in a few months because of factors relating to nVidia... A bit confused about that, but I think someone said that once the 600 series fills demands for all price/performance levels this will happen.
Just curious, this is this a pro or a con?
Does the extra power allow higher level overclocks? I think I finally found something to replace my 4890.
The only reason you'll find 2 6-pin connectors is that the card consumes more than 150W, because the PCI-E connector can deliver up to 75W and one 6-pin connector can also deliver up to 75W. You won't ever find 2 connectors on a card that draws less than 150W.
For example, the HD4850 and the GeForce GTS250 both need less than 150W, that's why you'll find only one connector on them, where the HD4870 and the GTX260 both need more than 150W, that's why you'll find 2 connectors on them. On the other hand, you'll find one 6-pin connector and one 8-pin connector on an HD4870X2 or GTX280, because they draw more than 225W (the 8-pin connector can deliver 150W by itself).
So it has nothing to do with dividing power over as many rails as possible, it's about specs, that's all.
You see, the 720W unit above has "only" 2 rails, yet it has 2 connectors, one of which is a 8-pin connector. If it was about having one rail on each connector, it would have had at least 3 rails ('cause one 8-pin would count for two 6-pin)
They said that one 6 pin can carry 75W, so it makes me wonder if splitting the one into two would mean providing less power to the card (though, after all, this xfx one is apparently no different in specs from the other brands, but it does use the board from the 7870 model).
Maybe someone else who knows more about this could confirm.
