So, after a long and grueling battle over a screwed up computer, I have been promised a replacement computer of "equal or better" quality. I believe I have been given 'worse' components on several of the parts. The problem is, I purchased my computer 2 years ago so many of the parts are no longer available. This means I have to compare some completely different technologies, and make a valid case for why the parts they gave me are insufficient. So, if anyone here is willing to help me out with the "Pros and cons" of any of these comparisons, I would greatly appreciate any input you could give me. A little bit of background information: This is a PC desktop. The main function of this is a gaming computer which needs to be able to handle some high stress 3D graphics. Onto the parts: (The Processor, motherboard, and video cards are what I think I have been jipped on.) Processors: Old computer: Intel Pentium D 930 (3.00 GHz) Processor Replacement: Intel Core2 Duo Processor E4400 (2.00 GHz) Now, All I know here is that 2 GHz is less than 3 GHz, and because of that I feel like I have been screwed. However, is there any reason that because it is a Core2 Duo, that would outweigh the loss of 1 GHz? Video Card: Old Computer: Nvidia GeForce 7300LE 64MB Replacement: Intel G965 Express Chipset Family Everything I have read says that the Intel G965 Express is Integrated Graphics, and I should avoid that like the PLAGUE if I want to game. I think this is a pretty clearcut case of just needing a dedicated graphic card instead of integrated, but if anyone could confirm that for me it would be great. Motherboard: Old Computer: ATI Xpress 200 Motherboard with 10/100 LAN Replacement: Intel G965 Motherboard Now, this I'm in the dark on ENTIRELY. My old computer was constantly bombarded with MB Errors. I'm not sure if it was related to the type of motheboard. However, this new motherboard obviously seems somehow linked with the integrated graphics card. If the graphics card is replaced, would a motherboard that supports a dedicated graphic system need to be replaced as well? I know -nothing- about motherboards. Speak to me about this as if you were explaining to a child, if you have any advice. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The following parts I believe are equal or better, but Im going to list them just in case anyone sees any faults. Hard Drives: Old: Seagate 200 GB 7200 RPM SATA Hard Drive w/ 8MB cache New: 250 GB 7200 RPM SATA II Hard Drive w/ 8 MB cache Memory: Old: 512 MB PC4200 533 MHz DDR2 Dual-Channel Memory Module New: Samsung 512 MB 667 MHz DDR2 SDRAM Memory Module Other than that, if anyone can give me a good reason to convince them I need Win XP back instead of Vista, I'd give you a hug. Haha. Thank you in advance for ANY input you can offer. Let me know if you need any other information.
