Overall Performance and Price Comparison

The overall results serve as a means of orientation and there is no weighting between benchmarks. The frame rates are simply added together; as a result, games with high fps results may balance out weaker resolutions.

The upgrade table shows the performance increase when changing from one combination to another. The individual benchmark results have been converted to percentages, but there is no weighting for extremely high fps rates.

Here is how to read the table: the vertical combinations in the column on the left are the starting points "from", while the upper combinations of graphics cards and CPUs are the upgrade "to". Where the two lines meet, you will find the value that represents the performance gained or lost, in percent.

The loss of performance can be at most -99.9%; otherwise the frame rate would be 0. The performance gain can be well over 100%, if for example, a frame rate rises from 1 to 10 or from 40 to 100 fps.

For between $464 and $541 (300 and 350 Euros), you can purchase a very fast combination of CPU and graphics card. Since the Q6600 at 3200 MHz is less than suitable for the boxed cooler, the price comparison has been calculated using a G0 stepping and Xigmatek HDT-S1283 costing $46 (30 Euros).

The E2160 and E6750 with the Geforce 8800 GT or 8800 GTS 512 is the best option, purely from a price point of view.

The extra cost for the Geforce 8800 GTS 512 is often acceptable, due to its better two-slot cooler. The Geforce 9600 GT with 512 MB is a better value for money, and very popular for those working with a budget of up to $186 (120 Euros).

    will there be a AMD/ATI roundup???

    That would simply consume more time without really proving much. I think sticking with a single manufacturer is fine, because you see the generation differences of cards and the performance gains compared to geting a new processor. You will see the same thing with ATI cards. Pop in an X800 and watch it crumble in the wake of a HD3870. There is no need to inlude ATI cards for the sake of this article.

    This has been a long needed article IMO. Now we can post links instead of coming up with simple explanations :D

    I didn't realize the new gpus were actually that powerful. According to Toms charts, there is no gpu that can give me double the performance over my x1950 pro. But here, the 9600gt was getting 3 times the frames as the 7950gt(which is better than mine) on Call of Duty 4.

    Maybe there's something wrong with the charts. I don't know. But this makes me even more excited for when I upgrade in the near future.

  • This article is biased from the beginning by using a reference graphics card from 2004 (6800GT) to a reference CPU from 2007 (E2140).

    Go back and use a Pentium 4 Prescott (2004) and then the basis of these percentage values on page 3 will actually mean something.

    maybe it is. but its relevant especially with those people who are stuck with those prescotts/6800gt. this article reveals an upgrade path nonetheless

    If they had used P4s there would be o many variables in this article that there would be no direction and that would make it pointless.

    Great article!!! It clears up many things. It finally shows proof that the best upgrade a gamer can make is a newer card. About the P4's, just take the clock rate and cut it in half, then compare (ok add 10%) heheh

    I know randomizer thinks we would get the same results, but would it be possible to see just a small article showing if the same result is true for AMD processors and ATi graphics.
    Firstly we know that ATi and nVidia graphics doesn't calculate graphics in the same way, who knows perhaps an ATi card requiers more or less processorpower to work at full load, and if you look at Can you run it? for Crysis(only one I recall using) you will see the minimum needed AMD processor is slover than the minimum needed Core2, even in processor speed.
    So any chance of a small, or full scale, article throwing some ATi and AMD power into the mix?
