Personally I buy everything I can from the same place, TigerDirect.com. I have been building computers for local businesses, city/county government offices, and individual users for several years all with parts purchased solely from them. My experience with them has been better than any other company I've dealt with in the past 20 years, bar none.
Since you've already been getting plenty of suggestions for products from Newegg, and you appear ready to make your purchases, I won't bother with listing my own personal suggestions. If the components you are expecting to buy offer the features you need, go for it. Just make sure you build it right, and abide by the warranties of all products. This means registering for everything the moment they arrive, just in case.
One thing that I did notice right away that might be of concern is your selected power supply. With the components list you have, I am not sure how well a <600w PSU is going to run for you. The price is fairly low for that SeaSonic model, but you are getting what you pay for: A less-than-common brand at a lower wattage rate. If you can spare the extra money you should try finding a good price for the Ultra modular series, namely their 600w or higher. I'm currently using the
600w Ultra X4 and it was well worth the price. And if you upgrade your video card later, add an additional SLI/XFire card, or overclock, then the added wattage will prove a great benefit. My previous X3 550w ran fine under normal loads, but sometimes struggled when running a lot of high-end components and graphic-intensive programs (and that was on my PC I built in 2004). This 600w X4 runs like a demon, with zero fan noise and very low heat output. I'm ready to buy their 1200w next time, that thing is pimp.
The rest of the components listed aren't "bad" (except the vid card, see below), but will leave you lagging a bit in a couple years. I prefer to build a new system only once every 4-5 years, so I usually tend to build the best that I can at the time (within certain budget limitations) so I'm not falling behind so soon. I can generally build a whoop-*** system for less than $1500-$2000 that will outperform most other gaming rigs of the time, and will still last me 3-5 years before a component finally fails or needs upgrading. Hell, I'm still using a 512MB AGP card, but will be moving up to dual 1GB PCI-E cards next time.
One last bit of advice, I noticed that the video card you listed was from Gigabyte. My recommendation would be to stay far away from that company, their products have always given me problems and their customer service is one of the worst I've seen in the industry. And I've been building custom PC's since the mid-90's. You're better off buying a terd on a stick.
The next video cards I grab in a few months will be 2x
these cards here, and you can buy two of these for less than one of those giga-nasty cards you linked.
Just in case you're wondering, I try to use cards with DVI and VGA output, DVI for my monitor and the VGA so I can hook it up projection systems or non-DVI monitors when I bring my tower with me to presentations.
For joysticks, it really depends on your personal preferences. You can get sets with separate throttle controls, or joysticks with the throttle built into the base. You can get rudder pedals, or get something like the Saitek that has a twistable stick to function as rudder. Button configuration is another important aspect, button quantity, layout, and response is something different people look at. Personally, I prefer to use one hand on the keyboard while the other uses the stick, so I like the buttons close to the top/middle of the stick, not the joysticks with dozens of buttons around the base. Again, it just depends on personal taste.
I've had a Saitek ST290 Pro for a few years now, and it still works perfectly. None of the buttons stick or "mis-fire", feedback is still smooth and responsive without any stickiness or stutter in stick movement, the base is large enough to help keep it in place without being so huge that it takes up too much room, and it offers good button placement in combination with a twist-stick rudder function. And if you're into buying from Newegg, they
have one available there for only $15. Can't get much better than that.
Oh, just a suggestion: If you ever do LAN parties or just want a PC so pimped that your friends will get chubbies just looking at it, you should try
one of these. Fits in a 5.25" slot and includes a cigarette lighter and pop-out cup holder. I used one of those on a custom-built PC for a customer, and even wired in an electric cup cooler into the base of the cup holder. Kept a can of soda/beer cold for hours.
