I would like to know if these items would be appropriate/compatible with the PC.
(2 x 2GB) DDR3 SDRAM AMD Memory Performance Edition. (replacing original 2x 1.5 ddr3 ram sticks)
Sapphire AMD Radeon HD 6670 1GB DDR3 PCI-E Graphics Card
Antec Basiq 350 Watt Power Supply (EDIT) Corsair Builder Series CX V2 500W is now what I have decided to go with.
I am sure the ram is compatible, and pretty sure the GPU is as well. But I'm curious as to wether that 350w PSU will do the trick. I read somewhere that the required PSU rating on graphics cards is just to cover the PSUs that don't put out even half as much as advertised to. Please all opinions are welcome. But I'm already pretty near spending limit, so even $30-50 more is pretty much out of the question. Please keep that in mind when making suggestions.
The reason why i chose a slightly more powerful gpu is because i was looking for something in my price range that would play d3 on low-medium settings.
That is a list of the supported and unsupported cards for D3.
Thanks in advance for your time.
EDIT I have decided to go with the Corsair 500w Builder Series PSU, but now I'm slightly over budget. Therefore I definitely cannot afford any price increase on RAM/CARD. Also I'm aware that there is 430w and it would probably work for my needs, but it is literally only $1 difference between the 430w and 500w (from where I'm purchasing at least). So that's why i went with 500
Don't use a PSU below the recommended requirements of a graphics card if you can avoid doing so. Those requirements assume that you don't have a bad PSU.
Also, there's no such thing as 1.5GB RAM sticks. Your computer has a single 2GB and a single 1GB stick. Still, replace both sticks with new ones. Maybe you can sell the old ones.
If possible, I would recommend getting something a little faster than the 6670. Maybe a 6750 or 6770?
The 6670 is not a powerful card at all (it's not a GPU, a GPU is a part of a video card. For example, the 6670 has a Turks GPU if I remember correctly). It is an entry level video card. It should do okay, but it wouldn't compare to a somewhat more expensive card (that is, if you can fit a better card in your budget). If you can't fit such cards, then maybe you can go for an older card. Older cards can provide more performance for the money, so they are often better buys for low budget systems.
