Upgrading a Computer System

I have been given a computer system and it's specifications and I have been told to make 3 hardware changes to suit the needs of a graphic designer. The system is as follows:

• Intel Pentium D "Dual Core" CPU (3.5 Ghz)
• VIA Chipset 1066 Mhz Motherboard - slots avaliable: AGP8x (1), PCI (3), RAM (2); ports available: LAN (1), USB (6)
• 512 MB RAM
• 80 GB HDD (SATA300)
• 18x DVD+/-RW Dual Layer & Dual Format
• onboard UniChrome PRO 3D Graphics with 64 MB shared memory
• mouse and keyboard
• 15" flat screen
• cheap inkjet printer

I am now going to identify 3 things that need upgrading and suggest improvements.
1) onboard UniChrome PRO 3D Graphics with 64 MB shared memory

• Because this is just a basic onboard graphics card it is not going to be very good at all. It also has 64 MB shared memory which could be improved greatly. To improve this I am going to suggest:
• Nvidia Quadro FX 2700M Graphics with 512MB DDR3 memory:
  This has a greatly improved memory capacity, 512MB rather than the really low shared memory of 64MB.
  

2) 512MB RAM

• 512MB is not a lot of RAM, and if I am dealing with a lot of images and have quite a few programs running then this RAM is not going to help me a lot. To improve this I am going to suggest:
• Upgrading to any RAM that is 4GB DDR3:
  Using this new RAM will give you an overall improved performance on your PC, reducing the risk of programs "freezing" or "not responding".
  

3) Cheap Ink Jet Printer

• A cheap ink-jet printer is not good for printing out images to a professional quality at all. To improve this I am going to suggest:
• Epson Stylus Pro 7880:
  This printer can print any size up to A1, allowing for a wider range of things to be printed off by the designer.

While trying to select a graphics card to upgrade to I came across two choices:
Nvidia Quadro FX 2700M Graphics with 512MB DDR3
and
Nvidia GeForce GTX 280M Graphics with 1GB DDR3 Video Memory
The lowest price I could find for the GeForce GTX 280M was £240.44 and the lowest price for the Quadro FX 2700M was £213.32. The GTX card is more expensive but comes with more graphics memory than the Quadro and this would be useful when working with graphics. Both cards are powerful enough to run the latest Adobe Suite without a problem. I would recommend the GeFore card as it is worth the extra bit of money as it is more future proof and reliable.
