The video card is not bad (I say this as its owner), but it's not the best choice.

Dear Major Vikhr,
I can offer you a *Celeron 3.0 Gz* for 800 rubles (BOX). Then the card will be good. And you won't need to spend money on a cooler.
I personally have a 256 mb 8600, as I already said. Everything is fine, as long as it's enough. I played *Crisis* on it without any problems. And so on. And it will definitely be enough for Heroes. All parameters on maximum.
So, let's consider the amount of money. And your 640Mb PCI-E GeForce 8800GTS is, in essence, a normal video card. If you take 95% of the games on the market, it will run them without problems. And why pay tens of thousands of rubles for monsters? Of course, the better, the better. But think about it, it's better to take a *mid-range* one than to overpay for a more expensive model, which, say, will drop in price by 40% in 5 months. But if you have the money, then you don't need to think about it. You go to a cool store, buy the most expensive system unit. But that's not for us, right?)
