I'm sure your current power supply could handle both cards. I've run the 9600 off a 350 watt power supply with no problem, so you'll be just fine. And don't pay attention to dominaz. I've run 2.0 cards in old slots without any problems before. I ran the 9600 in a board that had an old p4 like you and that was a 2.0 card. You can use either card you mentioned without problems.
You can use both-4350 is decent.Its not the same card when ATI launched it.It's performance was seriously degraded due to the passive cooling system ATI initially powered it with.Now it uses 40mm fan and yuuuuuup...The performance goes up---I have a 1366x768 res TFT and the frame rates for cod6 are 35-40 avg(using FRAPS sometimes 65 also)cod5 25-35 avg...This card is an example of how a bad cooling system can cause performance issues.Anyways it's still a low end card for HTPC soln.Yesterday i was playing bad company 2 on it at avg 20-21 FPS(FRAPS).However rather than using 5450 you can opt for HD 5670-Its the best card you could possibly get without upgrading to a new PSU(Rs 2500 app).It cost about 5500Rs here in kolkata ..Its GDDR5 DX 11 and will definitely provide you a Hi-Fi GAMING Experience at that resolution...
You can also get NVIDIA GTS 240..Its a little down in performance ..DX 10..Price Not sure
