I'm looking to make a HTPC as cheaply as possible. I already have a Pentium G620, an MSI microATX motherboard, 8 gb of ddr3, an Intel 80 gig SSD but unfortunately my motherboard doesn't have HDMI out. I recently came across a very cheap micro atx case with 300w power supply. The card will need to be low profile to fit the case and I would prefer bus powered. I would like to spend as little as possible on the card and was considering a Radeon HD 5450 vs Radeon HD 6450 vs. Geforce GT 610 vs. GeForce GT 210. The card will be used almost exclusively for video playback (I have a separate PC I game on). I would also like a silent card if possible as well. Any thoughts or opinions would be appreciated. Thanks y'all!
