I was planning to get a ati radeon 7770 but it needs a pci-e x16 lot. I have a Acer veriton m420. In the specs it has PCI Express® 2.0 x16 graphics card support I don't know what that means. So can I get the graphics card. I know that I need a new power supply and I am getting a 500 watt one.


I also have an 32 bit oerating system and do i need a 64 bit or can I still use my 32 bit for the card and a Athlon II x4 640 processor?


Also, I have an integratede ati radeon hd 3200 card, what does integrated mean? Can I pull it out and replace it or is it stuck?

The thing is that I researched my computer and it has Two 5.25"drive bays
Six 3.5"drive bays (two external, four internal)PCI Express® 2.0 x16 slot
PCI Express® 2.0 x1 slot
Two PCI v2.3 (5 V) slots
