A new computer bought from a shop with the same parts I used would have cost nearly 3000€ (about 3600$) not to mention I only saw one in a store once.
But, as for your question, I would suggest you check if your motherboard has AM3 or AM3+ support. Then for the processor, try this:
AMD FX 6200, AM3+, 3.8GHz. It is a very powerful, six-cored CPU that will last for years and run any future game with ease. Its estimated price would be about 148€ (177$), but it is worth every penny/cent/sestertius/whatever. Bear in mind that it might require you to buy a separate cooler also, if the old one is insufficent.
For the graphics card, a really good one is any of the Saphire AMD Radeon 6000-series with 2gb of memory, or if you want to be posh or if you are loaded with cash, then you could even try the new 7000 series. Although it is worth knowing that, for example, a HD 6950 with 2gb of memory runs games far better than a 7750 with 1gb. You can get a HD 6900 series for under 100€ (that is under 120$) Just make sure that
1. Your power source can run it
2. It fits with your motherboard (which in this case is extremely likely.)
