Advice Needed: Replacing GT430 w/ HD5670?

[Weznezz]

Hi guys basically my nVidia GT430 failed and is to be either replaced or refunded.
I've noticed the HD5670 for near the same price as the 430 and I know its has a rough performance increase of about 30% BUT:

I run multiple monitors and so I also use an ATi HD2350 x1 in my system which isn't going to get replaced.
I run Windows 7 Pro 32bit and have heard people running into problems when they use two same brand/different model cards in their system.
So far the nVidia + ATi combo has worked flawlessly so should I stick with the diff brands? or will the ATi + ATi be fine?

Also (slightly keeping on topic here) I chose the GT430 & HD5670 because they dont require the 6-pin adaptor. Are these the current best cards of their brand in this factor? Or are there more powerful cards out there?


Thanks in Advance

Ah I've sorted it
bought the 5670 anyway as i've read elsewhere that it should be fine. And if not, I have an 8400GS at hand anyway (and can use for physx woo)

an 8400gs is pretty useless for physx, probably worse than just using the cpu. but the 5670 is better than the 430, good choice.
