What is your budget for the tower?
What will you be using the rig for?
What resolution will you be running it on?

I'd say get a MSI, ASUS or Gigabyte motherboard with the Z77 Chipset (1155 socket) and either a 3570K or 3770K (if you're feeling fancy) processor.
As for memory, 1600 is enough for most people, 1866 would probably be the limit of what most people would actually need, but this all does depend on things like overall budget and so forth.
Graphics cards are much more power efficient than previous generations, so this means 1000W power supplies are often unneeded. You could do SLI or Crossfire with a 650W PSU with either Nvidia GTX 670s or AMD 7870s as an example. Currently there really isn't much difference in performance between the two gpu makers, so I would just get whatever tickles your whistle, personally I lean towards the Green Team (Nvidia). As for power supplies, Corsair, Seasonic and Antec are usually good power supplies to invest your money in.
The argument could be made that next AMD 8350 processor will be a huge improvement over the disappointing 8150, I personally wouldn't hold my breath... if you don't mind waiting for a few months you could see how the new AMD CPU stacks up.
All of this does depend on how much you're willing to spend though. A couple things I wouldn't cheap out on though would be:
Power Supply
Monitor
Keyboard
Mouse

Do you know That Most Amount of money you want to spend this will help Us ?

The Z77 chipset would be much better for having the option to go with multiple gpus in the future, and would probably offer better overclocking options. The H77 chipset is essentially just a scaled back version better suited for single card performance.
For a power supply prepare to spend around $100, don't cheap out on this component, because if you get a cheapy... when it goes it could take the rest of your internal components with it.
Depending on your needs a decent motherboard (Ivy/Sandy 1155, AM3+ 990FX) can range from the $130 to $250.
If you need a new case, you should think about what you want to fit in it, do you want room for possibly going multi-graphics card? As well as overall build quality and layout. Generally for a mid-tower roughly $70 to $130 is enough.
When it comes to monitors, just think of them as one of the parts that you'll probably hold onto the longest, the part that you'll looking at for a number of years. So get something that gives decent performance. Right now 1080p seems to be the "in" resolution, so I would at least get something with that. When it comes to price, size model, it all depends on your needs, personally I really like what Samsung is doing right now and I think 23/24" is a good size.
As for keyboard and mouse, it really does depend (and if you need a new one) Just don't get a cheap $10 keyboard, you'll probably regret it. For non-mechanical keyboards spending around the $20-50 range is pretty common. Since you mentioned guild wars, I would get a mouse that has one of those side buttons that you can hit with your thumb for voice chatting push to talk. (pet peeve against hearing people breathe while playing a game with them >_>; )
