So, after playing the BF3 beta, I've come to realise that my 9800GTX is not going to cut it anymore, so I'm in need of a new GPU.
I'm not quite sure what sure what GPUs would be suitable for use in my ageing desktop, so I'm looking for suggestions. At this stage, I would prefer a GTX 560.

• I'm ephasising stability over performance (so, no pre-overclocked cards)
• I'm on a strict budget. Best if it's not over 250USD.
• I would rather avoid Leadtek cards for now.
• I'll most likely be shopping from Umart, a local online retailer. I have yet to try an overseas-based retailer for computer components, but I don't mind as long as it's reliable and ships to here for a reasonable cost.

Spoiler for Current computer specs:

I'm also looking for suggestions for a new widescreen monitor. Preferably between 17-22 inches and under 400AUD (buying locally). Not too fussy about brand and features, but it should have a DVI port as a minimum, and perhaps a HDMI port as well (HDCP compatibility). I won't actually buy monitor yet, but any suggestions I'll keep in mind for a future purchase.
Thanks in advance!
