Besides the fact that most of these cards are really overpriced, there really isn't much else to say about these high-end cards. For the best price/performance, we recommend you take a look at the mid-range or ultra high-end cards. For the amount you would be paying here, you would be better off going with an ultra high-end card. Still, let's take a look at what we have available.
Here we have the GeForce 7800GS cards that come only in AGP form. There is a great selection of these cards available, but the best price we can bring you as of today is the eVGA GeForce 7800GS CO 256MB [RTPE: 256-A8-N506-AX] for $280 shipped, with a $15 mail-in rebate knocking the price down to a total of $265. As you skim through the rest of the chart, you will notice that there are many cards available for under the $300 price tag. Competing with the X850 XTPE, the 7800GS does an excellent job at filling out the top of the NVIDIA AGP performance spectrum. It is slightly underpowered compared to the X850 XTPE AGP, but the 7800GS is priced about $120 less. Honestly, we have to say that you're better off upgrading to a PCI-E motherboard and graphics card for an extra $100, but it's far easier to change graphics cards than to swap out an entire motherboard.
ATI's X850 line is rather interesting, as it performs better than the X800 line and is currently priced lower. The AGP cards are still pretty expensive, but the Sapphire Radeon X850XT 256MB [RTPE: 100106] priced at $165 is actually more of a midrange price with high-end performance. This is about the only "high-end" card that we would seriously recommend right now, and how long it stays in stock at this price is anyone's guess. Also note that CrossFire X850 cards are relatively expensive, and R400 CrossFire really wasn't a very elegant solution. We recommend you stick with single X850 cards if you plan on purchasing one.
It isn't really much of a deal, but the Gigabyte Radeon X800XL 512MB [RTPE: GV-RX80L512DE] is somewhat interesting, currently priced at about $200. (Ooooh! 512 MEGA-bytes!) Still, there's no point in getting this over one of the similarly priced X850 XT cards. The X800XT cards are also overpriced. For the price of these X800XT cards, you can easily purchase a 7900 GT or even something faster. Really, these cards are on the way out, and basically we're just seeing the last few remnants being sold.
What can we say that we haven't said before? Skip these cards over and head on to the ultra high-end cards if you're looking to spend anywhere near the amount these 6800GTs are going for. (And don't even think about the 6800 Ultra cards!) Alternatively, check out the next page for our mid-range batch of cards. Several of them will at least match performance of the 6800 GT, but do it at a lower price.
