Hello. I'm making my first build and I have a few questions. Currently I'm at: Biostar TZ77XE3 i5-3570K Corsair Vengeance 8GB (2 x 4GB) Kingston HyperX 3K 120 GB SSD and I already have the mouse, keyboard, monitor, and blu-ray drive. 1. Is it necessary to have a video card? I plan on gaming eventually, but not until I can afford a good gpu. This build is already close to $1000, and I still have to get the psu and case. 2. I have no idea what kind of psu to get. Any recommendations? 3. Any possible improvements I can make to my current build that won't cost me more money? I'd be willing to downgrade, but I don't want to sacrifice too much quality.
