I have a amd A8 8100 with a 600w inland d1011 psu would that be enough power for 2 r9 280x cards in cross fire

More about : 280x crossfire 600w psu

PSU doesn't sound like it's high quality, and you'd likely run into a bottleneck via the CPU. But even if you want to go ahead with the dual 280xs, your powersupply would not be enough.

Thanks. That's what I was afraid of. Would a single 770 or 780 be a better route

Bottlenecks vary by the game as well, but the greater the difference in performance between the CPU and Graphics component the greater is the likelihood that a bottleneck prevents the GRAPHICS CARD from using its full performance (it gets its data from the CPU so if that's too slow it's just waiting).

You wanted to go CROSSFIRE (AMD) but then asked about NVidia. I agree it should be a SINGLE CARD, however there are Pros and Cons to both choices of AMD vs NVidia cards.

Currently however, you can get a nice GTX770 for about $340 with three great games (Jan 31st 2014 expiry but redeem ASAP).

NVidia has the ability to record via Shadowplay and in 2014 will support G-Sync monitors, PhysX, Shield. AMD has 3GB cards for the same price and Mantle (Mantle may matter in a couple years but BF4 is the first game to use it once the update comes out).

So my advice is one of the GTX770's depending on availability. The Asus, MSI or EVGA with good cooler, or the 3xWindforce Gigabyte.

*You still won't get the same performance as you would with an i5-4670K for example, but as I said bottlenecks vary between games so it's difficult to draw the line where it's pointless to get a better card. I'm drawing the line at a GTX770 or similar AMD card.

Here are three GTX770's. I like the Asus most but it's slightly more money. All three are great cards and fairly similar in most respects:

The ASUS card has a backplate to help prevent warping over time but I don't know if that's a big issue.

*NOTE the three games:
- Batman Arkham Origins
- Splintercell Blacklist
- AC 4 Black Flag

Would you recommend those cards on a 600w PSU?

a single 280x or 770 would be the absolute most id put with that cpu, even then, still cpu bottlenecked in most games.

So if the 280x and 770 push the limits of my CPU it sounds best to go with the 280x as it is considerably cheaper

well the 280x and 770 are pretty much on par performance wise, trade blows depending on game/settings used. so if 280x is cheaper, that would be your best bet.
