The HD7770 is definitely a step up, though I guess the real question is whether your processor can actually keep up with it. Still, it’s probably a solid choice if you're looking ahead.
As for that power supply, I'd honestly swap it out sooner rather than later, especially if you're planning on running the HD7770.
Just unscrew four bolts and unplug the connectors—nothing too crazy there. If you've been running that power supply until now, you don't really need anything fancy; any basic 400W unit should get the job done. I guess if you let us know where you're planning to shop, we could maybe suggest something specific.
Just a heads up, if you're looking at the 9800 series, they were known for failing quite a bit, so I guess a lot of them ended up getting "fixed" in an oven.
Usually they don't even bother fixing it; they just swap it out for a new one. I guess you'd have to ask how long that actually takes, though. In my experience, they got everything sorted for me in maybe two or three weeks.
Eric Nguyen said:I checked out some gameplay online with that card. People are playing Call of Duty: Modern Warfare 3 and Grand Theft Auto IV, just go on YouTube and see for yourself. I'll test it out first, then decide—if my games actually run, I'm buying it; if not, I'm passing. Thanks anyway, but what 1 GB card would you suggest instead? 😁
Look, how many MB or GB a card has is pretty much irrelevant. Why? Manufacturers love to slap a ton of memory on a weak card just to look good, but that extra capacity goes totally to waste... This GeForce GT 210 wouldn't even use a third of it. The actual model matters most, followed by the memory speed (GDDR5), bus width, and stuff like that.
The GeForce GT 210 is bottom-of-the-barrel stuff and isn't really meant for gaming. You can find anything on YouTube, but a lot of those videos are fake. Just try it out, and if you get lucky, grab it—but don't expect to actually play anything besides maybe low settings at a tiny resolution.
