Radeon HD7750 and 1920x1080 monitor

[qbar24]

Hello, I've recently been thinking about buying Gigabyte Radeon HD7750C (880mhz instead of stock 800), a decent GPU for its cost (and my Fortron 350w). The spec will be as follows:

Intel G620 (maybe OC to 2.75GHZ from stock 2.6, not sure yet)
AsRock H61M-VS
4GB DDR3
Gigabyte Radeon HD7750 880mhz 1GB GDDR5
Fortron 350w
250gb HDD SATA II

The problem I seem to have is choosing a monitor. Finding a 16:10 1680x1050 monitor which isn't insanely overpriced is almost impossible where I live (Poland), so I guess I will have to go with BenQ G2222HDL. It's a 21,5' and has a native resolution of 1920x1080. As we all know HD7750 isn't a powerful GPU, more of a low/mid range. My question is about scaling down to 1680x1050 or 1680x900 while gaming (especially Guild Wars 2, yet to be released) - will I notice severe decrease of quality when doing so? Or anything 'unwanted' like black stripes here and there? Of course it would be perfect to play at monitors native resolution but being realistic, I don't really think this will happen very often in terms of yet-to-be-released games. Any thoughts on that?

notice: I'm not a native speaker and if you are not able to understand any part of the post above, please do tell. I'll try to be more specific then.

thanks in advance !

you dont want to overclock with that power supply
when using lower resolution the pixels will be bigger, you will see blocks around things that are rendered on your screen. you can counter that by using anti aliasing that will smooth out the jagged pixels

Or you could play in windowed mode - that's what I used to do with my HD 5670.

How about 20 inch screen 1600x900? would it be better? I don't really like windowed mode but thanks jessterman
