- The board specifies "VGA card required" because of the chipset that's in use. Intel's current consumer processor lineup all have an integrated GPU. Not all of their chipsets can actually access it - the Z68 chipset used on that motherboard can. It doesn't, however, have video ports, thus, a discrete card is still required.
- A better case might be larger/have more expansion, cool better and/or accomodate more robust cooling systems, have easier cable management, be lighter (aluminum), or just fit the aesthetics you prefer. As mentioned, higher end ones might include more fans out of the box too.
- Effectively, yes. Your biggest power draws, other than the CPU, tend to be video cards - so usually you'd just consider what you plan to use there. It's best to get something that has
some headroom, but also isn't complete overkill as it's both more expensive, and probably not in an optimal operating range.
For a single card, 550-650W is normally plenty. Dual card, 750-850W range more.
- SSDs, currently, are used mostly for system drives. What they particularly excel at is seek time - your OS does tons of looking at little files all over your HDD. IE, you open Photoshop, and it jumps around to check config files, registry settings, plugins, fonts, etc. SSDs blow HDDs away when it comes to accessing those files quickly. They also tend to do rather well with data transfer speeds n' all too...but the cost per GB right now is way too high to use them for bulk storage.
In general, an SSD is about the biggest upgrade you can make for system responsiveness. Typical setup would be an SSD for boot/OS/apps, and then HDD(s) for media, games, that sort of thing.
- Neither major graphics OEM (AMD or nVidia) actually produce their own cards right now. They'll make a chip, make a reference design, and then various brands market cards. There are plenty of good OEMs - PNY and XFX are solid, Sapphire on the AMD side, ASUS and Gigabyte tend to be decent, etc. Often the user reviews are a good indication.
While there are plenty of hardware sites to check on,
Tom's Hardware's monthly graphics guide is usually pretty good. Should be updated again soon I'd think. Just keep in mind that it's a fast-moving market - price shift a lot, and so would recommendations as a result.
- I personally have two HP 24" IPS monitors, a LP2475W and a ZR24W. The former is more expensive ($590 or so), but has a boatload of inputs (Composite, S-Video, Component, VGA, DVI, Displayport, and HDMI). The one out now is a v.2 of some kind.
The latter is a little less expensive (I bought it at a promo price when it came out, but it's like $510 now) and has only basic inputs.
Expensive compared to some...but not for a 24" IPS monitor. Neither are perfect, but I've been generally happy with them. Still, I'd say to hunt around. I usually check the discussions
here.
