HDMI capture card / PS3 connected to PC

[n-ster]

I'm interested in connecting my ps3 to my pc.

- My monitor doesn't have a scaler, not even a pixel doubler, so I can't connect to the monitor directly (Korean monitor)

- I can be laying my PS3 then just pause, alt-tab and check my email, that would be awesome!

- Perhaps my 7970 can enhance the image? I don't want to have too much input lag though

I only need 720p, but 1080p would be a very nice bonus. I DO NOT NEED the capture ability, so if there are cards that basically is an HDMI input, I'd rather have that. I found that AverMedia has nice solutions (Avermedia Game Broadcaster HD, Live Gamer HD or their cheap AverTV HD DVR thingy). What concerns me is input lag. I don't want to have to deal with a 300 ms + lag. I can tolerate 100, maybe 200 idk. Do you guys know what would suit me the best?
