What is the ideal amount of RAM for this system?

I have the following budget system that I created myself. It's really bare bones at the moment and the motherboard is pretty budget but I want to add a new graphics card and more RAM

Asus H81M-A Motherboard (2 RAM slots, PCI Express 1.0, H81 Chipset)
Intel Core i7 4770 with Integrated HD 4600 graphics
2GB RAM
500GB Western Digital HDD (6 gbp/s)
430W Corsair PSU

So what is the ideal amount of RAM? The 2GB is temporary and not dual-channel but I was thinking of expanding it to either 4GB (2GB x 2) or 8GB (4GB x 2) soon. I use my PC mainly for normal browsing and some light gaming right now. I notice that sometimes my PC freezes up and uses 70% ram with just 2-3 tabs open, during games it performs fine though.

Also, if I am allowed to ask, will a graphics card work in PCI Express 1.0 if the card is labeled PCI Express 3.0?

My motherboard specs:
1 x PCIe x16
2 x PCIe 2.0 x1

The card I want to buy is a budget AMD Radeon 7750 1GB GDDR5 (http://www.amazon.co.uk/Graphics-Express-4600MHz-Eyefinity-Technology/dp/B007R1SQ1K)

I know the board is only m-ATX and limited but I was wondering if that graphics card would work in that PCI Express 1.0 slot.

Thanks all and I hope I didn't post this in the wrong section or ask too many questions.




 
Solution
Sorry reread your OP. Yes that card would work with your MB and fit into your PSU power budget. PCIe 3 cards are revers compatible with PCIe 2, which you have on that board.

First, if you're not gaming and only using the system for browsing and media then you don't need an independent video card.

The more ram the better. In consideration of only having 2 slots, go 2x4GB, or better 2x8GB. You could get away with just adding a single 4GB or 8GB stick, giving you a total of 6/10. You still wouldn't have the performance benefit of dual channel, but the difference between dual and single channel RAM performance is marginal for most common applications.
