Is there a maximal finite depth infinite index irreducible subfactor?

I want to upgrade my Gaming PC In-Depth specs below. Help Thanks?

• Current Windows Experience Index:5.9 CPU:7.1 Memory:5.9 Graphics:6.6 Gaming Graphics:6.6 Primary Hard Disk:5.9 My PC is the HP Pavilion P6000. I'm wanting to upgrade the RAM, CPU and the HDD, but the problem i'm having is i dont know what is compatible with my PC. Most of the information ive got about the items inside are. RAM:4GB 2RX8 PC3 HDD:WD1001FAES <-- Think its a part Number. Motherboard:HP Part Number "612500-001" Thats all i could get from taking the cover off. My Budget is around 700 Pounds to upgrade so i then have a more powerful Gaming Platform. If you think i could so with extras or other new components mention it below also any websites provided will also help Thanks.

• Answer:

  Interesting situation. With a couple of upgrades your computer could be very good for gaming. But pushing beyond "very good" to make into a really high-end gaming computer isn't too cost-effective. Here are the details on your computer. http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=c02538176 Good CPU (Core i5 650), good amount of RAM (4GB), nice sized hard disk (1TB) - the only real problem is the graphics card- GeForce GT 320, which is quite low-end. That's basically just an earlier version of the GT 520, a low-cost card sufficient for everyday work and watching movies. It can also play easy games like the Sims, Minecraft, even Call of Duty 4 on low/medium settings, but that's all. It's just a £33 card, and real gaming cards start around £80-100. The graphics card determines 70% of your gaming performance, it's by far the most important component for gaming. Just replacing your GeForce GT 320 with a GeForce GTX 550 Ti or Radeon HD 6770 would quadruple your fps in games! http://www.techpowerup.com/reviews/Zotac/GeForce_GT_520/7.html However, even those are just low-midrange cards. At just £115, the Radeon HD 6850 is much better than a HD 6770 (the renamed 5770) or GTX 550 Ti. And for £125 you can get the even faster Radeon HD 6870. http://www.ebuyer.com/search?q=radeon+hd+6850&x=0&y=0 Midrange to high-end card performance: http://www.tomshardware.com/reviews/radeon-hd-6790-barts-gpu-geforce-gtx-460,2917-5.html http://www.techspot.com/review/359-nvidia-geforce-gtx-560ti/page7.html Next issue- better cards require more power. The factory psus in name-brand computers like HP & Dell are usually 300 watts- just enough for low-end cards. So installing a good graphics card requires upgrading you psu, too. A good 500-550W power supply can support any graphics cards up to the £200 price range, while 650-750W can handle really high-end cards. http://www.ebuyer.com/264380-xfx-550w-core-edition-pro-psu-p1-550s-ukb9 http://www.ebuyer.com/257233-corsair-tx-750w-v2-psu-80plus-bronze-certified-cmpsu-750txv2uk So a GPU and PSU upgrade are the essentials. For example, with the XFX 550W power supply and Radeon HD 6870, you'll have a very good gaming computer (capable of playing all current games on high settings and many on ultra/maxed) and won't have spent more than £180. You could go a level higher with the Radeon HD 6950, and only have spent £270. Assuming you go for the beefy 750W power supply, £290. Going beyond that point get dicey... Dell's case may not be large enough for a GTX 570/Radeon HD 6970 to fit, or have good enough airflow for such cards to function without overheating. You'd want a gaming case like a Cooler Master HAF 912. Its designed to handle the heat output of such cards, the stock HP case isn't. You have a good sized HDD, although it's filling up. Do you have a large library of music or movies? I'd recommend adding a 2nd 1TB drive or possibly an external drive and moving stuff off your main drive. No games utilize more than 4GB of RAM, not even the highest-end titles like Battlefield 3. So you don't need to upgrade there- going to 8GB is just future-proofing your machine. But since RAM is currently cheap, go for it. Anything beyond 8GB is just wasting money. Only video editing or 3D design workstations benefit from having 12-16GB of RAM. Your CPU is the real sticking point. It's a socket LGA 1156 Core i5. Not bad, but it's only a dual-core, not enough for ultra detail in high-end titles. Upgrading to a quad-core like the Core i5 750 or 760 would be much better for running high-end games. You could also upgrade to a Core i7 860. However those are in short supply. And they aren't high bang/buck- compared to 2nd-generation Sandy Bridge processors, any socket LGA 1156 processor isn't a good value. Going to a Core i5 760 (quad-core) would cost £155: http://www.ebuyer.com/229999-intel-i5-760-2-8ghz-socket-1156-8mb-l3-cache-retail-boxed-processor-bx80605i5760 While a Core i7 870 would be £242 (way too much) http://www.ebuyer.com/172757-intel-core-i7-870-2-93ghz-socket-lga-1156-8mb-l3-cache-retail-bx80605i7870 Those are unquestionably better, just expensive for what you're getting. Notice that both are below the performance of the new Core i5 2400, which only costs £148. http://www.xbitlabs.com/articles/cpu/display/core-i5-2500-2400-2300_7.html#sect0 But your motherboard can't accept newer Sandy Bridge CPUs. For those you'd need a new motherboard. And replacing the motherboard on branded computers like HP requires buying a new copy of Windows, since the pre-installed OEM versions are restricted to that specific manufacturer's motherboard. A Core i5 2500, new motherboard, new case, another copy of Windows 7 - you'd be looking at another £375. Yes it's doable, but a real project. The Core i5 760 along with a Radeon HD 6870 & 500-550W psu is probably the most bang/buck.
