Built in '09 for non-gaming:

Monitor: 1920 x 1080
Power Supply: Corsair 400CX (+12V@30A)
CPU: i5-750
Motherboard: MSI P55-GD65
Memory: 4GB (2 x 2GB) DDR3
Hard Drives: Intel X25-V and 7200 RPM SATA
Case: 120mm (front), 120mm (rear)

Stock clock but obviously power supply is the issue. What's the best card I can run? GTX 460 look nice but not sure it could handle it.

You could go with a HD 5670 1GB:

Maybe someone else has some good recommendations. Your power supply is the limiter, although I always hear Corsair can go above their advertised wattage, I'd personally not do it unless I had to. The GTX 460 is a much better card than the one I mentioned but asked for 450W... I'd ask some experts if they think that is wise with your supply.

Alternatively, you could up the PSU and then get a nicer card.

Actually you may be fine with the GTX 460, it only asks for 24A, so you might be safe.

at least a HD5770 for that resolution and power supply. the HD6850 and HD6870 use less power than a GTX 460 so you could go for them aswell.

I see the HD6870 uses less power than the GTX 460 1GB. I'm going to wait for the GTX 560 release and see how it compares to the HD6870. Found this thread: so hopefully OK on power supply. If I have to upgrade the power supply I know I'll probably be tempted to SLI/Xfire :( 

Thanks Pallimud, infernox, G00fy!

No problem, just remember, the harder you run your power supply, the faster it begins to degrade. So best to get the card that is the closest to the 30A you have. I had a card that required a little more power than my advertised PSU rate, but it ended up working, but a year later I had to get a new supply to continue running the card (the computer was fine, just not load with the card). Corsair is better though.

Hope you find what you are looking for.

corsair cx400 only has 1 6-pin pci-e cable but the HD6870 and GTX 460 use 2. so you will have to use a molex to pci-e adapter. the HD6850 though, uses 1 and performs similarly to the GTX460.
