great excuse to upgrade my 5750 to a 6970 ^.^ should be here tuesday.
Upgrade? Surely you mean support?
Use both cards for mining, a highly overclocked 5750 will net you up to 200MHash/s.
That's 40-something per cent of what you might squeeze out of that 6970, surely nothing to scoff at.
Do keep in mind that even those two cards working together might barely make up for the electricity the rig using.
A single card really won't be able to do much - even amortize the power usage of the mining rig let alone earn you some money.
As I already told you
a PSU upgrade does seem warranted.
Aim for a 650W unit for those two cards (or 750W to allow future GPU upgrades) - these PSU sizes are still relatively cheap.0% fee only pools:

is not free - they do take a percentage of your rewards)P2pool
being pretty well represented here (a bit overrepresented actually), why don't you give Eclipse
It's an excellent hop-proof DGM payout scheme pool.
Please note that Double Geometric Method
means that your revenue is offset in time: you will earn slightly less than expected on your first day but when you stop mining, you will still earn bitcoins for a few rounds.
As DAT said, BitMinter
is a great choice as well - as long as you don't mind the variation. This pool offers a proprietary, very easy, Java-based miner you can launch with a single click at the website.Eligius
is a SMPPS pool totally unaffected by either pool hoppers or block length variation.
