Very few people will appreciate any benefit of running two graphics cards. If you do want to go that route, even if that is a remote possibility for the future, look closely at your motherboard specs for bandwidth of the PCIe slots when both are in use. What was a 16x slot may well be limited to only 8x or worse 4x depending on the board's configuration.

There were lots of issues with the R290 AMD cards at launch as they got the drivers wrong. That is effectively sorted now. Even so, don't get stock cards and get ones that the manufacturer's have added their own dual / triple fan coolers and they will do for most people.

Put it this way , you aren't building a cutting edge super PC, but keeping sensible with your budget. That has to dictate your components and there will always be arguments why you should get something better, but you have to stop somewhere. Again you can wait for something else that will be released in a few months, but by then something else will be coming soon. When you make the decision to buy you have to work with what is available now for the budget you have and it seems that a grand is more than enough. Everyone posting here has different viewpoints on what makes a good PC. They would all work of course, but are they as good value and balanced or is the advice coming from the enthusiast who considers performance the priority and money secondary?

It is worth looking at some of the bundles and prebuilt systems available from the likes of scan, overclockers etc. Not because you have to buy one, but because they can give a good guide of a balanced machine at your price point.
