1. Yes
2. Yes
3. Yes
Not sure how HC a gamer your mum is but a X4 620/HD 5850/770 chipset build would be fine too if $$ was an issue

On your PSU, yes it's quite strong although I feel the 850HX would be more appropriate for crossfire and the Antec TP-650 or HX650 would be more appropriate for a single card build.

Since the board you have chosen has more limited PCI-E lanes, it would not be a great choice for two 5870s... so I think you should not plan on that and get the Antec TP-650.

Also try to find cas 7 RAM instead of the cas 9 you have picked out.

The x8/x8 slots are only a 4% difference.
And I think that crossfire with the 5870 only requires a 600w PSU according to the AMD website.

Did you see modern comparisons somewhere or are you thinking about the old comparisons done with 4870s? I was assuming the 4% had grown with stronger GPUs, but if there are modern comparisons I would like to see them.
Otherwise I would expect up to 10-12FPS drops in demanding games on a 790GX setup.


As to the PSU, CF 5870s at stock speeds will pull 400W, all 12V, by themselves.

Technically this means you could use a very good 600W PSU, if it had all the connections you needed and didn't mind the heat and having the PSU wear out in 2 years.

As you will be pulling 550W or more at peak loads and you ideally want to have that around 60-70% of your PSU rating, you end up with the more realistic 750W, 850W ideally.

OK so i can keep the MB i picked and do crossfire with it just it will run 8x 8x and not 16x 16x?

It doesn't make a lot of sense to me to spend 820 dollars on GPUs and $100 on a motherboard. It's like buying a GMC engine and putting it in your Kia.

Unless we are talking about a monitor running at 2560 x 1600, or 3 of them, then CF 5870s would be overkill also.
